• How Fix 100% CPU usage on Windows

    How Fix 100% CPU usage on Windows

    If your computer’s cooling fan often runs at high speed, your CPU is overloaded. This means your computer will slow down. It’s really annoying if you don’t fix it.

    CPU (short for Central Processing Unit) is known as the processor, the key brain unit of the computer. Just like our brain, when it has to process too much information or perform a heavy task, it will become overloaded. Similarly, if you have to perform different tasks when overloaded, the processor will also slow down when it has to respond to many tasks at the same time.

    Usually, you can avoid this by interrupting some active applications. But CPU capacity can get out of control by the chaos of some processes like WmiPrvSE.exe. However, there is an easy fix for the high CPU consumption error.


    To check if it is the cause, open Task Manager and search for the WmiPrvSE.exe handler. If you see CPU capacity higher than a few percent, and cannot run any programs related to the function of this process, then this is the cause.

    Task Manager window

    Microsoft once released an official fix that can prevent this problem quite effectively. However, sometimes this solution can’t fix it completely, you can’t download it, then try restarting the process manually. Use the built-in search engine on the Windows Start button and then search with the keyword Services. In the window that appears find Windows Management Instrumentation and right-click it and then press Restart. You can stop all this process if you want.

    Cài đặt Services

    In a worse case, your computer may be infected with a virus, you will see 2 WmiPrvSE.exe processes running. Now you need to use an anti-virus program to kill the culprit.

    System Idle Process

    Windows users frequently see high CPU consumption through System Idle Process. This process seems to show all CPU power.

    System Idle Process program

    System Idle Process is the process that indicates the processor is idle. This process is used by the very complex nature of coding for the processor to run some operations instead of not running to make it more efficient and compatible. But this is not a Windows process, so if you see it appearing in the Task Manager and think it is taking up computer resources and slowing down the computer.

    If your computer is normal, you will see that this process takes up about 95% of the CPU when the computer is in idle mode. If not, it means that there is a program that is taking up resources and making your computer slow.

    Many processes are running in the background

    A background process is a program that is running on your computer even though you do not open its window. Computers will usually have several running in the background at the same time to operate the processor. However, the cause of the problem is that users often install additional programs on their computers over the years.

    You can check the processes by disabling this background running in Task Manager from Windows Search or taskmgr.exe. By default, the Processes tab will display all processes running in the background. To avoid confusion, you should turn off all other programs before doing this. Note that these typically only take up 10% of the processor.

    In Windows 10, open Startup in Task Manager.

    Programs running in the background

    For Windows 7, exit Task Manager and open msconfig.exe via the Windows Search or Run box. In the System Configuration window, open the Startup tab.

    Now uncheck the unnecessary programs and click OK, then restart the computer. This will prevent these programs from starting.

    Antivirus program

    When scanning hard drives, antivirus programs can consume large amounts of processor space. This does not affect newer computers or high-end laptops, but it will be overwhelming for older devices.

    Antivirus program

    Fixing this error is quite easy. Almost all antivirus applications have a function that allows users to schedule automatic scans. So you just need to adjust the scan time of these programs to the time when the machine is not in use and you will no longer be bothered.

    Or perhaps a virus

    On the other hand, malware can also be the cause of this phenomenon. An infected program may run in the background or may attempt to spread by sending malicious software to others via email, the network, or other sources. They all need handlers that reduce their power.

    However, determining whether your computer has a virus or not is often not an easy task and sometimes we have to rely on…feeling. If your computer doesn’t have any antivirus software installed, try downloading one of the highly rated free antivirus programs like Avast! Free Antivirus, AVG, Microsoft Security Essentials 2014… conduct a full system scan.

    With luck, the virus will be removed, your computer will return to normal. And if CPU overload and slow machine still occur, you should consider reinstalling Windows.

    Svchost.exe (netscvs)

    When checking the Task Manager, you should also pay attention to Svchost.exe (netscvs), which is also one of the processes that can be the cause of high memory consumption and CPU overload. They are legally associated with malware; it is a critical Windows system process. When unsure if it is working properly, use the Lookup Tool. If it’s not associated with malware, it’s busy scanning for plug-and-play devices.

    To rule this out, go to Control Panel > Network and Sharing Center and click Change advanced sharing settings. Then, select Turn off network discovery.

    Change sharing preferences

    Svchost.exe also shows increased activity while Windows is downloading updates. Usually you will find it using 25% or more CPU capacity after you install Windows. In that case, just let Windows Update do the work.

    In Windows 10, you cannot delay or pause Windows Update easily. You can only schedule the installation of new updates if needed. This inadvertently causes svchost.exe to take up CPU memory. What you can change, however, is whether your computer shares downloaded updates with other devices. So disable this feature to save bandwidth and processing power.

    Go to Settings > Update & security > Update, check Advanced options, and then press Choose how updates are delivered, and enable Off or limit PCs in the same network.

    Selection of Windows Updates

    Another workaround to fix this issue that is related to downloading those updates is to temporarily disable Windows Update. This will prevent Windows from downloading updates. However, we do not recommend this solution.

    The power supply is faulty

    This is an issue that can affect both Windows 10 desktop and laptop users. If the power supply fails (power cable on a laptop, PSU on a desktop), it can start an undervolt CPU to maintain power. When underperforming, the CPU can only operate at a fraction of its full capacity, manifesting as 100% CPU usage on Windows 10.

    Faulty power supply can cause CPU overload error
    Faulty power supply can cause CPU overload error

    To solve this problem on a laptop, it is quite simple: Unplug the laptop from the power cable, then click the battery icon in the bottom right corner of the Windows 10 desktop, click Battery Settings > Power & Sleep Settings > Additional power settings, and select High Performance. If the problem is with power, then CPU usage should return to normal in Task Manager (Ctrl + Shift + Esc).

    On a desktop, things can get a little more complicated, as you’ll need to remove the PSU from your PC and test another PSU. You should check out the other tips listed in the post before trying this.

    Superfetch (or Windows Search)

    Superfetch is a process where Windows 10 learns which apps you use most often and then prefetches them for you so they load faster each time you use them. This is a constant background process that usually doesn’t cause problems, but it doesn’t always work well with older devices.

    To find out if Superfetch (or another service) is hogging your CPU, open Task Manager (Ctrl + Shift + Escape), click More details, then select CPU to sort processes by amount CPU they are using.

    If you see a “Service Host” like Superfetch or something else that is using a lot of CPU, you can try right-clicking it and selecting End process.

    Disable Superfetch
    Disable Superfetch

    Alternatively, you can press Win + R, type services, and then scroll down to Superfetch in the Services box to permanently stop it (or until Windows turns it back on, which can happen after you update your operating system).

    Right-click Superfetch, select Properties, then in the Properties window, click the drop-down menu next to Startup type, select Disabled > OK.

    Permanently disable superfetch
    Permanently disable superfetch

    Refer to other ways in the article: How to enable and disable SuperFetch on Windows 10/8/7.

    Technically, you can do this for any service that is hogging the CPU, but some services are very important to the system, so you need to be careful. Another culprit of high CPU usage is Windows Search, which you can also safely disable.

    Power plan is not suitable

    Cycling in Windows power options can significantly affect PC performance. If you have it set to “High performance“, especially if you’ve changed the “plan settings,” you’re probably overloading your CPU (again, older devices are more prone to this problem).

    Power plan được đặt thành “Power plan set to
    Power plan set to “High performance” may overload CPU

    Type power plan into the Start search bar, then click Choose a power plan. If you are using High performance or Power Saver then switch to Balanced.

    To be sure, click Change plan settings, and then on the new screen, click Restore default settings for this plan.

    CPU overload is a global problem

    It’s hard to monitor an overloaded CPU. While the issues listed here are among the most common, CPU usage can still be an issue even if you try everything suggested above.

    Also, you can see how to fix this error with TiWorker.exe on Windows 10/8.1/8.

  • 5 Ways to Fix a Windows Computer Screen That Doesn’t Turn Off After Set Time

    5 Ways to Fix a Windows Computer Screen That Doesn’t Turn Off After Set Time

    Windows 10 will turn off the screen after a certain amount of time, allowing you to rest without turning off your device or going to sleep. In addition, it can keep your information from prying eyes and save some power if you are using the laptop without the charger plugged in.

    If that doesn’t happen on your Windows 10 PC and the screen stays on, there may be a problem with the settings. This guide tells you which settings you should change so that Windows turns off the screen after the set time.

    1. Check Power & sleep settings

    Power & sleep is the first setting that you need to check. Here’s how you can do it:

    Step 1: Click Start, then go to Settings > System.

    Step 2: From the left, select Power & sleep.

    Step 3: Check out the Screen section.

    Step 4: If the options are set to Never, you need to adjust them again. You can set options when the laptop is on battery power or when the computer is plugged in.

    Check Power & sleep settings
    Check Power & sleep settings

    After you have changed the Screen settings, look at the Sleep settings. Although you can turn on your laptop or PC while the screen is off, it can create conflicts if the Sleep settings are not appropriate.

    To avoid any problems, make sure the On battery power, PC goes to sleep and When plugged in PC goes to sleep after options are set to Never.

    2. Run Power Troubleshooter

    The computer screen that does not turn off after the set time indicates a power related problem. This is why running Power Troubleshooter can fix the problem. Here’s how you do that:

    Step 1: Click Start, then go to Setting > Update & Security.

    Step 2: From the left, select Troubleshoot.

    Step 3: Click Additional troubleshooters and scroll-down Find and fix other problems.

    3. Search for apps running in the background

    An app can keep running without you realizing it, and it prevents your device from turning off the screen or going to sleep. For example, the Windows 10 assistant, Cortana, can continue to be activated by certain keywords. Also, if you have open cloud storage or any other online sync application running, you should close it.

    The best way to fix this is to check the Task Manager:

    Step 1: Right click on the taskbar and select Task Manager.

    Step 2: Select Processes tab.

    Step 3: Select an application and click End task.

    Search for apps running in the background

    Step 6: Click Apply > OK.

    Check the advanced power settings
    Check the advanced power settings

    5. Examine Peripheral Devices

    When USB devices keep disconnecting and reconnecting, they prevent Windows 10 from turning off the screen. You can fix this problem by unplugging all USB devices like a keyboard, mouse, external hard drive, etc. and checking if this solves the problem. If this fixes the problem, connect your devices one by one to find out which USB device is causing the problem.

    In the event that the problematic USB device cannot be identified, it is recommended that you run the Windows 10 troubleshooter. As it may take a while to run the individual troubleshooter for the keyboard, Bluetooth, or printer, then you should use the Hardware and Devices troubleshooter.

    Follow these steps:

    Step 1: Open Command Prompt with admin rights.

    Step 2: Type:

    msdt.exe -id DeviceDiagnostic

    Step 3: Press Enter button. This will open the Hardware and Devices troubleshooter.

    Step 4: Click Next to begin the troubleshooting process.

  • How to fix 502 Bad Gateway error

    How to fix 502 Bad Gateway error

    The 502 Bad Gateway error is an HTTP Status Code (HTTP Status Code) error, which means that one server received an “invalid” response from another server.

    1. What is a 502 Bad Gateway Error?

    502 Bad Gateway Error Message
    502 Bad Gateway Error Message

    Every time you visit a website, your browser sends a request to the web server. The web server receives and processes the request, and then sends back the requested resources along with the HTTP header and HTTP status code. Normally, the HTTP status code is not seen unless there is a problem. It’s basically the server’s way of notifying you that something went wrong, along with code on how to diagnose the problem.

    There are different types of 500 status error codes (500, 501, 502, 503, 504, 520, etc.), and their meanings may differ slightly. These errors indicate that the request was accepted but that the server prevented the execution of the request. In this case, the 502 Bad Gateway error specifically means that a server, while acting as a gateway or proxy, received an invalid response from the inbound server.

    How Does SEO Affect by a 502 Bad Gateway Error?

    Unlike the 503 error, which is used for WordPress maintenance mode and requires Google to check back later, the 502 error can have a negative impact on SEO if not fixed immediately. If the site is down for an extended period of time, say more than 6 hours, Google may consider the 502 error to be a site-level issue that needs to be addressed. This can affect your rankings. If you are worried about 502 errors repeating, you should find out why they are happening. Some of the solutions below may help.

    2. Signs of a 502 Bad Gateway error

    The Bad Gateway error on each site will be different. However, if you encounter a Bad Gateway error, you will see one of the following error messages:

    “502 Bad Gateway”

    “502 Service Temporarily Overloaded”

    “Error 502”

    “Temporary Error (502)”

    “502 Proxy Error”

    “502 Server Error: The server encountered a temporary error and could not complete your request.”

    “HTTP 502”

    “502. That’s an error.”

    “Bad Gateway: The proxy server received an invalid response from an upstream server.”

    “HTTP Error 502 – Bad Gateway”

    The 502 Bad Gateway error displayed in the Internet browser window is similar to that on the web page.

    “Fail Whale” is one of Twitter’s “infamous” errors, and the essence of this error is the 502 Bad Gateway error.

    The Bad Gateway error in Windows Update typically generates error code 0x80244021 or the error message WU_E_PT_HTTP_STATUS_BAD_GATEWAY.

    When Google services, such as Google Search or Gmail, encounter a 502 Bad Gateway Error, it usually displays a Server Error or, in some cases, simply displays a 502 on the screen.

    3. The cause of the 502 Bad Gateway error

    Typically, the bad gateway error occurs as a result of a problem between online servers over which you have no “control.”


    The Microsoft IIS web server management system usually provides more detailed information about the cause of the 502 Bad Gateway error by adding additional parameters after the 502, such as HTTP Error 502.3: Web server received an invalid response while acting as a gateway or proxy.

    4. Some solutions to fix the 502 Bad Gateway error

    As mentioned above, the cause of the 502 Bad Gateway error is due to a server failure or a problem that you cannot control.

    To fix this error, you can refer to some solutions below:

    Method 1: Reload the URL again

    Try reloading the URL again by pressing the F5 key or clicking the Refresh / Reload button.

    The 502 Bad Gateway error occurs because the server is down for an upgrade; it is only a temporary error, so you can apply the solution of reloading the page again to fix the error.

    Method 2: Restart your browser

    Close all windows on your browser, then open your browser again, and try opening the website you want to visit again.

    The 502 error that occurs may be because your computer has a problem while you are browsing the web in the browser. The simplest way to fix the 502 error in this case is to restart your browser.

    Method 3: Clear your browser’s cache

    “Outdated” or corrupted files stored in your browser can be the cause of the 502 error. In this case, just clear the cache files and try to open the page you want to access.

    Refer to the steps to clear the cache on your browser here.

    Method 4: Clear browser cookies

    “Outdated” files or corrupted files stored in your browser can be the cause of the 502 error. If you have applied the solution to delete the browser cache files, you still cannot. If you can’t fix the 502 error, you can think of a solution that is to delete cookies on your web browser to fix the error.

    Refer to the steps to delete cookies from browsers here.

    Note: If you do not want to delete all cookies from your browser, you can search for and delete cookies associated with the website that returns a 502 error.

    Method 5: Start the browser in Safe Mode

    When your browser runs in Safe Mode, it will run with default settings without add-ons, extensions, or toolbars.

    During the process of running the browser in Safe Mode, if the 502 error does not occur, then you can confirm that the cause of the 502 error is due to extensions or browser settings. Then you just need to reset the browser settings to their default mode or find and disable the extensions that are the cause of the error.

    Note: To run the browser in Safe Mode, you just need to start your Windows computer in Safe Mode and run whatever browser you use.

    Method 6: Use another alternative browser

    You can use an alternative browser, such as Chrome, Firefox, Internet Explorer, Microsoft Edge, or Safari.

    If you have applied the above solutions and still do not fix the 502 error, you can use another alternative browser to browse the web. If the 502 error does not appear in other alternative browsers, the cause of the error may be something wrong with your native browser. You can then uninstall that browser, then proceed to download and reinstall the browser to fix the error.

    Method 7: Using Software Update 1 for Microsoft Forefront Threat Management Gateway (TMG) 2010 Service Pack 1

    If you have installed MS Forefront TMG SP1, and in the process of accessing a certain website, you receive the error Error Code: 502 Proxy Error. The network logon failed. (1790) or other similar error messages.

    You can then download and install Software Update 1 for Microsoft Forefront Threat Management Gateway (TMG) 2010 Service Pack 1 to fix the error.

    DOWNLOAD Software Update 1 for Microsoft Forefront Threat Management Gateway (TMG) 2010 Service Pack 1 and install it here.


    This solution is not a general solution to fix the 502 Proxy Error error, but is only applicable in some specific cases.

    Method 8: Restart your computer

    Some temporary problems in the process of your computer connecting to the Internet can be the cause of the 502 error. This case is very simple; you just need to restart your computer to fix the error.

    Method 9: Restart network devices

    Sometimes, in some cases, problems with modems, routers, switches, or other network devices can also cause 502 errors or 502 Bad Gateway errors. In this case, you just need to restart the devices—modems, routers, switches, etc.—and you’re done.

    Method 10: Change DNS

    Modify the DNS settings on your servers, routers, computers, or devices. Bad gateway errors can occur as a result of temporary DNS server issues.

    Method 11: Contact the site directly

    This is also one of the good solutions to fix the 502 Bad Gateway error. Chances are that in many cases, the site is down and the site’s administrators have not “fixed” the error, which is the cause of the 502 Bad Gateway error.

    You can visit the Website Contact Information page to see a list of contacts for some of the most popular websites today. Most websites have social media accounts used to support their services, and some even include email and phone numbers for users to contact.

    Method 12: Contact your Internet service provider

    The final solution to fix the 502 Bad Gateway error is that you can contact your Internet Service Provider to find the cause and fix the error.

  • 8 ways to fix malfunctioning screensavers in Windows 10

    8 ways to fix malfunctioning screensavers in Windows 10

    Windows comes with a lot of personalization options, one of which is screensavers. You can place any design, image, or text to add some fun to your screen during a break. However, sometimes screensavers stop working, leaving you with a blank and boring screen.

    If your computer does not display screensavers no matter how long you wait, the following guide from Thewindowsfan.com will help you fix this. In addition, the article will also guide you on what to do when the screensaver freezes or when you cannot exit the screensaver mode.

    1. Turn on screensavers via Settings

    By default, Windows screensavers are disabled. So, if you don’t recall configuring this setting, you’ll probably need to enable it in Windows settings. Follow these steps to enable the screensaver and personalize it:

    Step 1: By pressing Windows key + I, you can access Settings.

    Step 2: Go to Personalization.

    Step 3: Select Lock screen from the menu on the left.

    Step 4: Click Screen saver settings.

    Step 5: Use the Screen saver drop-down menu to select screensavers. You can check the appearance of screensavers by clicking Preview.

    Step 6: Use the field next to Wait to set after how many minutes of screen inactivity the screensaver will start working.

    Step 7: Click Apply > OK to save the new screensaver settings.

    Turn on screensavers via Settings
    Turn on screensavers via Settings

    If you want to lock your computer when the screensaver starts, select the option On resume, display the logon screen. Also, set the timeout to one or two minutes when you turn on the screensaver for the first time so you can check if it works properly.

    Note: If you have not activated Windows, you cannot adjust the settings of screensavers.

    2. Disconnect any external devices that you no longer need

    If you have a screensaver set up and it doesn’t activate, try removing some devices that you no longer use. External devices such as joysticks, cameras, or headsets may prevent the system from activating screensavers.

    If you’ve unplugged all unnecessary devices and your screensavers still won’t start, you should look into other options.

    3. Change the time the computer goes to sleep

    If the computer takes less time to go to sleep than it takes to activate the screensaver, you will never see the screensaver. This is because your computer was in sleep mode before the screensaver was activated.

    To fix it, you need to adjust the time the computer goes to sleep or the screensaver timeout. Follow the steps outlined above to change the screensaver timeout. If you want to adjust how long the computer goes to sleep, follow these steps:

    Step 1: Open Settings.

    Step 2: Go to System > Power & sleep.

    Step 3: Under Sleep, use the drop-down menu to set a new time.

    Change the time the computer goes to sleep
    Change the time the computer goes to sleep

    Note: Set a new time for both the On battery power, PC goes to sleep after and When plugged in, PC goes to sleep after options.

    4. Examine the Presentation settings

    Windows has many tricks up its sleeve that you may not be aware of, and Presentation mode could be one of them. While this is great for business environments as it doesn’t interrupt your speech, it will also turn off screensavers.

    To disable Presentation mode, right-click Start and go to Mobility Center. Then, click the Turn Off button under Presenting. If you want to check more settings, click the Projector icon.

    Examine the Presentation settings
    Examine the Presentation settings

    5. Run Power troubleshooter

    If you can’t find anything wrong with the screensaver settings, it’s time to turn to Windows troubleshooting tools. Running the Power troubleshooter can fix problems with screensavers.

    Step 1: Click on Start and go to Settings > Update & Security.

    Step 2: From the left, select Troubleshooter.

    Step 3: Click on Additional troubleshooters.

    Step 4: Go to Find and fix other problems.

    Step 5: Click on Power > Run the troubleshooter.

    Run Power troubleshooter
    Run Power troubleshooter

    The troubleshooter will fix any problems found on its own. Then check if the screensaver is working or not.

    6. Run an SFC scan

    System File Checker will repair any corrupted system files or problems that prevent screensavers from functioning properly. Launch the Command Prompt with admin rights and use the sfc /scannow command to start the scan.

    This can take a while, so make sure you or anyone else doesn’t close the Command Prompt window. If any corrupted or problematic files are found, SFC will automatically replace them.

    7. Reset power plan settings

    Because screensavers are a power feature, some incorrect power settings may prevent screensavers from activating. In this case, reverting the power plan settings to default will fix the problem. Here’s how you can do it:

    Step 1: Open Control Panel.

    Step 2: From View by menu, select Large icons or Small icons.

    Step 3: Open Power options.

    Step 4: Click on Change plan settings > Restore default settings for this plan.

    Reset power plan settings
    Reset power plan settings

    8. Update the monitor’s driver

    If your computer screensaver works but freezes, you should update your display driver.

    Although graphics card drivers are usually updated through Windows updates, it is likely that you are using drivers that are not included in Windows updates.

    In this case, you can update the display driver manually through Device Manager. Here’s how you can do it:

    Step 1: Type device manager in the Start menu search bar and select Best match.

    Step 2: Expand the list of Display adapters.

    Step 3: Select Update driver from the context menu when you right-click on the graphics driver.

    Step 4: In the pop-up window, select Search automatically for drivers.

    Update the monitor's driver
    Update the monitor’s driver

    You can also find available updates on the manufacturer’s website, as long as you make sure you’re installing one that’s compatible with your system.

    Good luck with your troubleshooting!

  • How to debug Windows applications with Process Monitor

    How to debug Windows applications with Process Monitor

    Do you have Windows 10 apps that aren’t working as expected? Maybe it’s too slow, crashes all of a sudden, or has loads of hard-to-identify problems. One way to get to the root of the problem is to use a free official Microsoft utility called Process Monitor. This tool will help you diagnose and debug any Windows application errors or problems.

    Download and install Process Monitor

    The SysInternals Process Monitor (ProcMon) utility has been around since 2006 and does much more than diagnose application problems. It provides the ability to view all registry keys, file system locations, and network traffic.

    However, it does not capture mouse pointer movements or hardware-related changes. If your goal is to catch malware, identify troubled applications, or get a high-level overview of your Windows PC, then ProcMon is the most advanced tool to have.

    • Download Process Monitor

    There is no need for installation, but you must accept the SysInternals software license terms before running the.exe file.

    Let Process Monitor list all the events on your Windows system. Any running programs are automatically included in the analysis.

    Diagnose problems with Windows Process Monitor

    When the program lists detailed information, you can be overwhelmed to see so many rows and columns. There are millions of entries. You don’t have to take care of everything; just pay attention to the following:

    • Process name
    • Process ID (PID): A four or five-digit number
    • File path
    • Result code: “Success” or more entries such as “name not found”, “Reparse”, etc.

    To quickly jump to troubled apps, go to Tools > Process Tree.

    Process Tree” width=”483″ height=”287″ />
    Go to Tools > Process Tree

    The dashboard will have all the applications open and running on your system. A complete green block in the “Life Time” column usually indicates there is no problem in the relevant application. If Windows 10 programs and systems are updated, many registry errors and file health problems won’t cause any trouble. For updating-related matters, you can use another utility called SetUpDiag.

    The green block in the “Life Time” column indicates there is no problem in the related app
    The green block in the “Life Time” column indicates there is no problem in the related app

    Scroll down to the problematic event and click “Go to Event” to navigate to the issue. In the next screen, ProcMon diagnoses many problems with Tencent’s QQ Browser. A process ID (“3428”) can be identified by its.exe file.

    Once the problem source is identified, you need to use an option called “Filters“. By right-clicking and adding the “Include” filter to a specific executable, you focus only on a specific application and then apply the filter. Depending on the number of entries, it may take some time. There are already thousands of entries in this filter.

    You can also exclude certain results like “Success” or “Buffer Overflow”, as they indicate the application is not crashing. This will narrow the search even further.

    Now, focus on the most common result code for the troubled application. The “Name not found” problem is the most common here, with thousands of entries, meaning the caller tried to open an object that doesn’t exist. In other words, the installation itself went wrong. Thus, you have diagnosed the root of the problem.

    The “Name not found” problem is the most common phenomenon
    The “Name not found” problem is the most common phenomenon

    Final Troubleshooting

    Here, the article will show the final troubleshooting for the above program. Before addressing a diagnosed issue that requires uninstallation, you may want to save the ProcMon file from File > Save so you can look into related issues in the future.

    Saving the file also gives you the filter presets you just created. If you want to go back to the default settings, click Reset.

    As shown here, the program needs to be uninstalled because many DLL files are missing. Uninstalling a program is not always easy, so ProcMon has a right-click option called “Search online”. It leads to the Uninstall screen.

    Uninstall screen
    Uninstall screen

    The program was completely removed after clicking the uninstaller.

    Clicking on the uninstaller removed the program completely
    Clicking on the uninstaller removed the program completely

    The uninstall step is a nuclear option (the “extreme” option), but it works with programs that have too many file-missing problems.

    When reopening ProcMon with the same filter presets, the problem with Tencent’s QQ Browser disappeared.

    You can use Windows Process Monitor to diagnose Windows application errors and resolve problems. It only takes a little effort to locate the main source of the problem.

    If your Windows is experiencing 100% CPU usage errors, see the solutions here to fix it. Thewindowsfan.com also provides solutions for incorrect system configuration information.

  • How to fix “This Setting Is Managed by Your Administrator” error on Windows 10

    How to fix “This Setting Is Managed by Your Administrator” error on Windows 10

    You may see the message “This setting is managed by your administrator” for the following functions in Windows Security:

    • Real-time protection
    • Cloud delivery protection
    • Automatic sample submission.

    Usually that means these settings have actually been configured by the system administrator, and it would make sense for you to discuss this with that person. But if you’re the admin, here’s what you can do to fix the problem:

    1. Check if you are using any third-party tools

    If you are using a third-party tweaking tool to enhance your Windows 10 security, it may have made these changes through the Registry or Group Policy.

    You may want to identify and uninstall this tool or use the Reset to Windows defaults button and see if that helps.

    2. Scan for viruses and malware

    The first and foremost thing you need to do to fix the problem is to scan your computer for viruses and malware. To remove malware, the article recommends that you do not use any third-party anti-malware programs. Instead, use Microsoft Defender.

    To do that, follow these steps:

    Step 1: Start Settings by pressing Win + I.

    Step 2: Clik on Update & Security > Windows Security > Open Windows Security.

    Step 3: Click on Virus & threat protection > Scan options > Microsoft Defender Offline scan > Scan now.

    Let your computer be scanned and deleted for viruses.

    Check if this fixes the problem. If this does not fix your problem, you can try the next solution.

    3. Delete Windows Defender Key

    Deleting the Windows Defender Key in Registry Editor has worked for some users and will certainly work for you. So to do that, launch Registry Editor from the Start menu and navigate to the following location.

    ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender

    Right-click Windows Defender, select Export, create a new folder on your PC (preferably on the Desktop), open it, name the file “Windows Defender” and click Save.

    Now do this for all subkeys and remove Windows Defender.

    Finally, restart the PC, and the problem should be fixed.

    5. Check Registry or Group Policy settings

    Now you may need a bit of expertise to do this. You have to check the settings manually.

    You can find the Defender settings in the Registry by following the path:

    HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Advanced Threat Protection

    And in Group Policy, go to:

    Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus

    You will have to check if any are in Configured state. You need to make sure they are not Not configured.

    Good luck with your troubleshooting!

  • 5 ways to fix the “Getting Windows Ready” error on Windows 10

    5 ways to fix the “Getting Windows Ready” error on Windows 10

    Windows has made great strides over the years and has become the choice of millions of computer users worldwide.

    However, for now, Windows 10 computers are still prone to random crashes. A common problem is that Windows gets stuck in the “Getting Windows Ready” loop. Thewindowsfan.com will go over some solutions to this error with readers in this article.

    5 useful ways to solve the “Getting Windows Ready” error

    Anything can cause this problem on Windows 10, Thewindowsfan.com has compiled the best methods you can take to get back to your workflow. Let’s start with the first and most basic way.

    1. Give Windows a little more time

    Patiently waiting for Windows to update
    Patiently waiting for Windows to update

    Sometimes the best thing to do is nothing. If you’re not in a hurry, consider leaving the machine running. It’s normal for the update process to take a while, especially if you haven’t updated your PC in a while or your Internet connection is slow.

    Try letting it update all day. If there is still no progress, then the problem may have another cause.

    2. Check your Internet connection

    Make sure you have a good Internet connection
    Make sure you have a good Internet connection

    As noted above, if there’s something wrong with the Internet connection itself, then you’re obviously going to have a hard time updating your PC. Double check to make sure that’s not the case and try to resolve the problem if this is the cause.

    If you are using a wired connection, consider the router. Unplug it, let the router rest for a bit, and then turn the router back on to see if that helps. If you are using WiFi, double check that it is working properly. If you think something is wrong, try some fixes or plug in an Ethernet cable.

    If you’ve tried the two methods above and are still having problems with the “Getting Windows ready” screen, you should try shutting down your computer.

    Note: Only try this method after having done the above methods.

    When Windows is updating, an abrupt shutdown can result in damage to important system files. You may even experience the dreaded blue screen of death error on your computer.

    Some might say that you won’t lose files after a forced shutdown, especially with the new componentization structure that comes with Windows Vista, called Component-Based Servicing. Even so, the article always advises you to act with caution and never bet against the system.

    If you decide to give it a try, here’s how you can go through the forced shutdown process: If you’re using a laptop, press and hold the power button until the system shuts down. After that, reboot the system, and you should see the updates downloaded again or the system will boot normally. If you are using a PC, simply disconnect the power.

    If everything goes well, your computer should be up and running again without any problems.

    4. Using the Startup Repair tool

    Startup Repair is a handy tool that can fix problems
    Startup Repair is a handy tool that can fix problems

    Startup Repair is a handy, free tool found in the System Recovery Options menu on Windows operating systems. It helps you automatically solve many complex problems related to accidental data loss, boot problems, and more. Follow the steps below to get started:

    Step 1: Create Windows installation media on USB. If you need advice on how to do this, follow Thewindowsfan.com’s instructions on how to create Windows 10 installation media on USB.

    Step 2: Start the computer with the USB and select the Repair your computer option from there.

    Step 3: From there, select Troubleshoot.

    Now, on the Advanced options screen, click Startup Repair.

    The Startup Repair option will start looking for errors and problems on the computer and then resolve as many errors as possible. Once the process is complete, shutdown and reboot to see if the problem persists.

    5. Perform a factory reset

    Factory Reset, as the name implies, completely erases the copy of Windows on your computer. It will then install a fresh copy of the operating system, just like it did when you first bought it. This is a handy tool from Microsoft that can rescue you from all kinds of Windows problems.

    Furthermore, it comes with two different reset modes: Keep my files and Remove everything. Keep my files will delete Windows and any additional apps and updates you’ve installed on it, but keep your documents intact. On the other hand, the Remove everything option will delete everything on the PC and then reinstall Windows from scratch.

    Good luck with your troubleshooting!

  • How to fix SearchProtocolHost.exe errors on Windows

    How to fix SearchProtocolHost.exe errors on Windows

    The Windows system is constantly updated to correct errors or address any problems or risks that previous versions may have had. So it’s no surprise that you will get different errors from time to time when using it. These problems can come from the system itself or from third-party apps installed on the device. Most of these errors can be fixed in a few steps.

    One of the problems you may encounter is the SearchProtocolHost.exe application error. If you are experiencing this issue, the following guide will provide some solutions to help you resolve it.

    What is the SearchProtocolHost.exe error?

    The SearchProtocolHost.exe process is part of the Windows Indexing Service, which indexes various files in the system so you can easily find them when you need them. This is an important process in the system. When you see it running in your system, do not remove or disable it.

    However, this process sometimes encounters errors. This problem is usually caused by an infected, corrupted, or missing executable file, which usually occurs when you start the computer. Here are other causes of this error:

    • The SearchProtocolHost.exe registry is invalid or corrupted.
    • The malware infection corrupted the SearchProtocolHost.exe file.
    • The SearchProtocolHost.exe file was accidentally deleted or infected by a piece of software unrelated to your Windows system.
    • A third-party program conflicts with the Windows system and some of its files.
    • SearchProtocolHost.exe is corrupted due to an incomplete download or installation.

    How to fix SearchProtocolHost.exe errors on Windows computers

    SearchProtocolHost.exe errors come in different forms. The most common error you will get when this process crashes is “SearchProtocolHost.exe – Application Error. The exception unknown software exception (0x0241938e) occurred in the application at location 0x000000006931759E“.

    However, you may also receive other error messages for the same problem, such as:

    • SearchProtocolHost.exe does not have a valid signature
    • SearchProtocolHost.exe stopped working
    • Microsoft Windows Search Protocol Host has stopped working
    • Outlook: SearchProtocolHost.exe stopped working
    • The instruction at 0x00f01e40 referenced memory at 0x00f01e40. The memory could not be written.

    If you experience any of the above error messages, follow the steps below to fix the problem on your Windows PC.

    1. Scan virus

    In some cases, you may see several SearchProtocolHost processes running on the Task Manager. This usually indicates that your computer is infected with a virus or malware, and you must clean your computer immediately. Some viruses disguise themselves as legitimate processes or, even worse, replace them.

    You can fix this problem by running a full system scan using Windows Defender or any third-party antivirus software if it’s available. If the case is serious, you need to perform a Windows Defender Offline scan when starting the computer. If the system fails to boot, you can also use the Antivirus Rescue boot media.

    After scanning and cleaning the system, check if the error is still there. If so, follow these troubleshooting steps.

    2. Repair files through an SFC scan

    If a corrupted file is causing the SearchProtocolHost.exe error, running a System File Checker (SFC) scan usually fixes the problem. This built-in Windows troubleshooter looks for any corrupted files in the system and fixes them for you.

    Note: Don’t panic if the scan takes a long time. Scanning time depends on the number of files on your computer. So if you have a lot of files, it may take longer than usual.

    3. Turn on the Windows Search service

    Sometimes, the Windows Search service is disabled, causing SearchProtocolHost.exe to encounter some errors. If this is the case for you, enabling the service may help fix the problem. Follow the steps below to check and enable the Windows Search service:

    Step 1: Press and hold the Windows key while pressing and holding the R key. Then type services.msc and press Enter. This will open the Services window.

    Step 2: In the Services window, look for the Windows Search service.

    Look for the Windows Search service
    Look for the Windows Search service

    Step 3: Once found, right-click the service and select Start or Restart, as appropriate, from the menu.

    Step 4: Then double-click the entry to open its properties.

    Step 5: In the General tab, click the drop-down box next to the Startup type option and select Automatic (Delayed Start). Next, check the Service status and make sure it’s running. Then, click Apply > OK to save the changes.

    Select Automatic (Delayed Start)
    Select Automatic (Delayed Start)

    Step 6: Close the Services window and restart the computer. Check if this fixes the problem.

    3. Uninstall the recent Windows update

    Some users have reported receiving this error after installing a recent Windows update. If you recently installed a new update, that could be the cause. Uninstalling it might fix the problem.

    4. Reinstall Microsoft Office

    If you are facing the SearchProtocolHost.exe error in a Microsoft Office application, removing it from the system and reinstalling it will usually fix the problem. Follow the steps below:

    Step 1: By pressing Win + R, you can access “Run.” Then type appwiz.cpl and press Enter.

    Step 2: Find Microsoft Office from the list, right-click it, and select Uninstall.

    Select Uninstall
    Select Uninstall

    Step 3: Follow the on-screen uninstallation procedure.

    Step 4: Visit the official Microsoft Office website and download it once more when it has been entirely uninstalled.

    Step 5: Install the app and check if the problem persists.

    SearchProtocolHost.exe is a legitimate and safe process on Windows systems. There are other processes in the system that you may encounter. If you see a strange process in Task Manager, don’t panic. Ending it right away can do more harm than good. Instead, do your research and check if it’s a legitimate process. If you discover that it is problematic, it is best to remove it and repair the system immediately.
