I experienced an unexpected electrical failure, actually lights flickering on and off over about a 20 second period. It was enough to make the desktop computer [without an uninterruptible power supply] restart several times.
All seems well with it, except all programs in the Start menu are shown as being "new", and whatever programs I had pinned to the start menu are no longer pinned, replaced with the standard Windows 10 apps.
It doesn't seem worth restoring the entire system from an image file, IF this was the only damage done... My questions are: where is the start menu configuration stored? And any idea what may have caused this "reset"? I ran a chkdsk on C: as well as sfc /scannow, and found no errors. So I'm a bit confused as to what may have happened.
