What the heck happened?
I installed the Trial version last night and proceeded to analyze, then clean-up my PC. It was taking a bit of time so I left and came back about an hour later and there was a message to restart my PC, so I clicked OK.
Then as it's restarting, Windows 10 was installing a lengthy update (this surprised me, I don't recall an update in pending status). Logging in took some time and then BAM!
That's not my desktop, all my Taskbar shortcuts are gone, no MS Office anymore, all my document folders/files/photos are gone... the disk drive free space is only a frac
