Re: Son's laptop wont update Win7
well took a final chance before a full clean install by doing a restore from the oldest restore point I found , had to do it a few times, but then it finally checked for updates properly = 180+ updates. Installed updates about 20 at a time and finally it is now fully functional.
Deleted all other programs such as thurnderbird, cashe files, temp files,etc.
Then reinstalled Thunderbird/Mozilla after creating another user account.
