This laptop is badged as Windows 7. It now has Windows 10. It won't restore (something like "restore not possible" as the error message) - not to 7 or 10. Is there some sign in any of the files present to show whether a path back to 7 exists? Is there some sign to explain why restoration to 10 fails?
I'm guessing MS doesn't want to facilitate a return to Win 7, but i'm wondering why a 10 restore won't work
