Hello @Arush47 


Please run the below commands in CMD. Ensure you run CMD as an admin. These commands will delete the Windows Update registry log on your machine and then next time you click on check for updates, WU will check against the entire WU database.


Reg delete HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate



Net stop wuauserv >NUL


Cd C:\windows


rmdir softwaredistribution /s /q


Net start wuauserv >NUL


I am sure this will help. Let me know how you get on.
