Hi JITHIN.R,
Based on your situation, please kindly try to reset the Windows Update components by below command:
Net stop wuauserv
rd /s %windir%\softwaredistribution\
Net start wuauserv
After that, if it doesn’t work, you could check windowsupdate log, the text file is located in C:\Windows\WindowsUpdate. In addition, if the log shows any error, could you please share the log via OneDrive? It would be very helpful.
Hope above information helps.
Best Regards
Tina Cao
