Bosses are jerks sometimes. Ask him tomorrow what he did or say you can't change it until he tells you...

This doesn't seem like a very pressing matter, OP. Your life certainly isn't fucked. Ask around. See if your coworkers know what it was like before he changed it. If all else fails, go to the big man himself! He can't exactly blame you for something he did. Good luck.

Best of luck finding it, that can be like finding a needle in a haystack unfortunately. Maybe one day someone will add an event log to the computer so you can see what was changed.

See if IT can help you. Just make sure you tell them you already "turned it off then back on."

That sucks.

Enjoy unemployment :D!

Sounds like a pointy haired boss, this looks like it's a case for the Dogbert Tech Support Line... Unless you wanted your computer problem to get better... Not sure who you'd call there... Ghost busters, perhaps?

Best of luck figuring that one out, if nothing else contact him or wait until you see him again and explain the situation

Honestly that's a dick move by your boss

hit the undo button till it doesn't have anymore things left....it only tracks them since when you saved the document
