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.
