Hi Jon,
I may have confused you--sorry if I did.
When I wrote "a clean reinstall," I meant a clean reinstall of Windows 10, wiping out the existing corrupted Windows 10 that Dave said "booted to a blue windows logo and spinning wheel of death."
There are usually fixes for Windows when it fails to boot, but they can be tricky and take longer than a clean reinstall.
Dave mentioned data file backups, but it didn't sounds as if he has a system image up his sleeve.
I don't know if AC 10's built-in .enc backups can be restored to get around the support-key on a clean reinstall of Windows 10 (as opposed to restoring a system image backup).
Again, sorry if I only confused things.
Cheers,
Carl Fogel
