I'm having some issues installing windows update on this particular Windows 7 PC. I'm trying to (for instance) install Service Pack 1, and its popping up an error saying "Element Not Found", and then marking it as failed with Error Code 490 : "Encountered an Unknown Error" (very useful).
This happens to pretty much all windows updates I've been trying to install.
So far, things I've tried:
- Virus Scan
- Error Scan
- Running two different Microsoft 'ifixit' related to windows update
- Running it in safe mode
- Running the SP1 preperation tool
- Downloading SP 1 manually and running that
- Force shutting it down, taking out the battery and turning it on again
This problem has been ongoing for months now.
Looking at the System logs I do see a lot of errors but they aren't giving any useful information "Not avaliable"
So far nothing has worked, anything else I could try? I can't format the PC unfortunately.
