Hi Sanjaya,
What's the exact error message when you try to install updates?
- Please run
winver.exeand post a screenshot of that dialog. It shows the OS version and build number. - Run the Windows Update Troubleshooter, which is based on the new "Get Help" platform. Visit https://support.microsoft.com/en-us/windows/troubleshoot-problems-updating-windows-188c2b0f-10a7-d72f-65b8-32d177eb136c#id0ebf=windows_11 and click "Run the troubleshooter in Get Help"
