I did just that lol. It also took a signature from me, and then my boss for them to back off.
At the end they returned a laptop that had half of the drivers missing, and regular windows installed on it without its license. (a license we were forced to pay for)
But that is all I needed, to get their grubby mitts out of our research tools. Got a fully functional Linux machine running half a day after that.
