A friend of mine had been contracted to record a webcast with a few fairly important and wealthy businessmen. The company that contracted him provided him with some equipment, they set up some slides to appear in the background, and then their Windows 10 laptop suddenly rebooted on my friend.

They delayed the webcast for about two hours, hoping it would come back, but the laptop didn't finish in that time so they just had to go without. "Funny" thing is that it was his reputation that took the hit, not Microsoft's nor the contracting company's.
