Update error

Hi

I bought this refurbished pc a couple of years ago with windows 11 home installed and started getting the update error message a week ago. I've tried quite a few 'fixes' found on the internet without success. One suggestion was to update the 21H2 version i have to a later one but when i run the system checker it says my cpu (i3 7100T) is not supported. Prior to this updates have installed without issue.

Any advice appreciated

Thanks in advance
