I just set up a client's computer, working great. Last night there was a request to do a Window Update and she said yes. When her computer restarted almost everything was gone as if a reset had been done. There is even a Windows.old folder with nothing in it. When I checked which update had been done it said, "Feature update to Windows 10, version 1607.
She is now getting the message -
We can't sign into your account
This problem can often be fixed by signing our of your account and ten signing back in. If you don't sign out now, any files you create or changes you make will be lost.
Needless to say we are very concerned. Fortunately she has a cloud backup but I hesitate to restore with this message. There are 2 TEMP users. She is signed in with the account that was created when I set up the computer, it is a local account.
Thank you for you help!
