Updates don't install on a Windows 7 Computer

Hello,

I was working on a Windows 7 computer and there is a pop up message that says: restart your computer to finish installing your Windows update. ( I have attached the message).

I restarted multiple times and also tried to completely turn off and on the computer but nothing happened, the updates won't install and that message keep popping up driving my clients nuts.

I also disable the updates warning but it didn't make any difference. Any suggestions on how to stop this please ?

Thank you,
