I just wiped and set up a laptop as a favour… It forced updating Windows (to 11, possibly?) before booting. No option to skip, and no indication how much it was downloading.

Such a pain. I had to wait an hour for it when it already had a fully functional OS. What can’t it download in the background and update at 3am when idle? That’s what made me suspect it was as forced Windows 11 upgrade, since why else would they care to force it?
