Ok, so I got home, turned on the computer, logged in and everything was gone. Documents (were still in the drives, but it was locating to the stanard folder, not D:\Documents, desktop, all settings, media library, everything - just like I had a new login.
So I logged out, to find it was still my only log in - I went back in, and ran system restore for the most recent point.
This messiage appeared;
, and everything is back to normal.
Odd or what?
