How do I fix unknown hard error in Windows 11?

Are you constantly encountering the Unknown Hard Error whenever you start your Windows computer, open a program, or interact with the taskbar? This frustrating issue usually occurs when the executable files associated with various Windows system processes, such as explorer.exe, ctfmon.exe, sihost.exe, and mcuicnt.exe, encounter failures. This particular error can prevent you from using your Windows 10 or Windows 11 computer properly and lead to abnormal behavior, such as missing desktop icons, screen flickering, a Blue Screen of Death (BSOD), and more. Luckily, there are a few troubleshooting tips below that can help you fix this annoying error.

1. Scan Your Drive for Errors:


To begin, it’s important to scan the system drive (where Windows is installed) for any corrupted data or bad sectors. You can use the Check Disk utility on Windows for this purpose. Follow these steps:
– Right-click the Start icon and select Terminal (Admin) from the Power User menu.


– When the User Account Control (UAC) prompt appears, select Yes.


– In the console, paste and run the following command: chkdsk c: /r /scan /perf


– Wait for the command to scan and fix any issues with your drive, then check if the error persists.

2. Run SFC and DISM Scans:


If the Check Disk tool fails to detect problems, you should perform scans on your PC’s system files using the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools. These tools automatically detect and replace damaged system files with their cached versions. Here’s how to do it:
– Click the search icon on the taskbar, type “cmd,” and select “Run as administrator.”


– When the User Account Control (UAC) prompt appears, select Yes.


– In the console, type the following command and press Enter: SFC /scannow


– After that, run the following commands one by one and press Enter after each one to perform the DISM scan:
– DISM /Online /Cleanup-Image /CheckHealth
– DISM /Online /Cleanup-Image /ScanHealth
– DISM /Online /Cleanup-Image /RestoreHealth
– Restart your PC after the scan is complete and check if the Unknown Hard Error still occurs.

3. Reinstall the Faulty App or Program:


If the Unknown Hard Error only appears when you try to launch a specific app or game on your Windows 10 or Windows 11 PC, there may be an issue with the installation of that particular program. Try reinstalling it to resolve the problem. Follow these steps:
– Press the Windows + R keyboard shortcut to open the Run dialog box.
– Type “appwiz.cpl” in the box and press Enter.


– Select the problematic program from the list and click the Uninstall button at the top.


– Follow the on-screen prompts to remove the program from your computer.
– Install the app or program again, and the error should no longer bother you.

4. Try a Clean Boot:


Another troubleshooting step you can take is to boot your PC in a clean boot state, where Windows will only run essential services and programs. This will help you determine whether the error is occurring due to a malfunctioning third-party app or service. Here’s how to do it:
– Press the Windows + R keyboard shortcut to open the Run dialog box, then type “msconfig” in the Open field and press Enter.


– Navigate to the Services tab and check the box that reads “Hide all Microsoft services.”
– Click the “Disable all” button.


– Switch to the Startup tab and click on “Open Task Manager.”


– Select a third-party app or program and click the “Disable” button. Repeat this step to disable all third-party apps and programs.


– Restart your PC after completing the above steps and try using it again. If you don’t encounter the Unknown Hard Error during a clean boot, one of your third-party apps or programs may be causing the error. You’ll need to remove any recently installed apps and programs one by one to fix it.

5. Install Windows Updates:


Microsoft regularly releases updates for Windows 10 and 11 to introduce new features, fix bugs, and enhance security. Make sure to install any pending updates to see if they resolve the Unknown Hard Error. Follow these steps:
– Press the Windows + I keyboard shortcut to open the Settings app.
– In the Windows Update tab, click the “Check for updates” button.
– Download and install any pending updates, then check if the error still occurs.

6. Perform a System Restore:


If you’re unable to identify the exact cause of the Unknown Hard Error, performing a system restore can help. This process will revert your PC to an earlier state when it was working fine. Here’s how to do it:
– Click the search icon on the taskbar, type “create a restore point,” and press Enter.
– Under the System Protection tab, click the “System Restore” button.
– Select the “Recommended restore” option and click Next.
– Review all the details one more time before clicking Finish.

By following these troubleshooting tips, you can resolve the Unknown Hard Error on your Windows 10 or Windows 11 PC. If none of these methods work, performing a system restore may be necessary to get your computer back to normal. Let us know in the comments which solution worked for you.
