I am trying to upgrade from Win 7 to Win 10. Before proceeding I installed all the required Win 7 updates, then attempted to install Win 10. However every time I try I get:
"Code 80070780 Windows Update encountered an unknown error."
See attached screen captures.
"Get help with this error" is not helpful. I've clicked "Try again" 4 times now, always the same problem.
Any ideas?
80070780 is a rather generalised File system Error - this would suggest to me that the actual install media downloaded for the upgrade has been corrupted
It's possible to download a new copy from Microsoft and use this to either Upgrade or Clean install
The Upgrade details are here ...
Windows 10 - Upgrade Installation - Windows 10 Forums
and the actual download is here ...
Windows 10 ISO Download - Windows 10 Forums
I downloaded the ISO file and burned to a DVD, then ran the setup. All seemed to progressing until I got the attached popup.
