How to fix these issues?
You can try out the following seven fixes.
Restart your PC
Restarting your PC is by far one of the most simple and effective solutions to just about any problem you run into while using Windows. Graphics issues, network problems, update glitches, rebooting got you covered.
It’s also not a bad idea to check your internet connection real quick. At times a dead or inactive internet connection can be the root cause of a lot of problems.
Disable any third-party antivirus
Microsoft has revealed that certain Symantec and Norton antivirus versions do not work well with this particular update. Try disabling or uninstalling any third-party security software that you might have on your PC to see if you can install the update then.
Run an SFC scan
Corrupt files are the number one reason why your PC might be behaving weirdly. Here’s how you can get rid of them and potentially resolve your issue.
Step 1: Press Windows Key + S to bring up the Cortana/Search box and search for Powershell. Open Windows Powershell from the search results.
Step 2: Type sfc /scannow to scan your system for issues.
Step 3: If the SFC scan finds any problem, use the following command to resolve them.
DISM /Online /Cleanup-Image /RestoreHealth
Restart your PC, and the error should be gone.
Run the Windows 11 update troubleshooter
Just like Windows 10, Windows 11 also comes with a bunch of helpful troubleshooters that’ll automatically detect and resolve any problems your PC might be facing. The same goes for the update troubleshooter, here’s how.
Step 1: Press the Windows key and search for Troubleshoot settings. Click the corresponding search result.
Step 2: Click Other troubleshooters.
Step 3: Scroll to find the Update Troubleshooter and click the Run button.
This should automatically fix the problem.
Restart the Windows Update Service
The Windows Update service is responsible for periodically checking for any new updates Microsoft may release. Restarting this service can help get your machine on track.
Step 1: Press Windows Key + R to open the Run prompt. Type services.msc and hit enter.
Step 2: Find the Windows Update service. Right-click it and select Stop.
Step 3: Return to the Services Console and restart the Windows Update service in step 2.

Install the latest version manually
If nothing else works, instead of relying on Windows updates, you can head over to Microsoft’s official download page and download the latest version of Windows manually and install it on your system.
Alternatively, you can also use the Media Creation Tool from Microsoft to install Windows 10 on a bootable flash drive and reinstall the OS on your machine.
The Windows Media Creation tool is a great way to install Windows and repair the OS. Using this, you can perform a clean installation or repair your OS without affecting your personal data.
