Hi, I've been trying to upgrade a 64-bit Windows 7 Home computer to Windows 10, but the process fails and rolls back win Win7. Putting the Win10 upgrade to the side for the moment, I've tried just running Windows Update, but that too fails. The pre-scan from Windows Repair shows 121 missing .cat files, and 1 corrupt .mum file. I'm clueless as to why and how that many are missing.
Can this many files be replaced somehow? Let me know if more info is needed. Appreciate any advice anyone may have.
