Hello, thank you for reaching out to Microsoft Q&A.
Run the Windows Update Troubleshooter:
Go to Start > Settings > System > Troubleshoot > Other Troubleshooters > Windows Update > Run.
Once the troubleshooter is finished running, restart your computer and check for Windows updates again.
If you are still having issues, run the System File Checker Utility scan:
Open the Command Prompt (Administrator) Window, run these commands one by one, and click Enter for each command.
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Restart your PC and check for Windows updates again.
Let me know if you are still experiencing the same issue.
