"But I have unplugged it... yes, several times... I'll try again... oh, it works now... now to my real problem, Windows now asks me for a 64 character code..."
Been there, done that. I don't remember where I retrieved that code, but somehow I managed to do that. Maybe it was on Microsoft site loggin in with his credentials.
Still a positive in my eyes. Somebody gets their computer stolen, or sells a computer not knowing that files can be read/recovered from the hard drive, and they're protected. Unless you're thinking you're gonna get raided by the government or something it fits most use cases while still letting people who forget their password recover it.
Funny you say that, because that was the case. If I'm not wrong he logged into his work account, which used just once on his personal laptop and MS Windows decided to encrypt the drive and connect it to that account. Funny stuff.
