One similar thing happened to me on windows 8 (except I wasn’t testing it, I lost everything on my pc that day because it didn’t just fail to update and restore…it just fucked my drive with it !), so it’s not even a new type of issue. Even windows 10 was fucked, had a friend who never used bitlocker, never even knew it was a thing, who got his pc encrypted by it after an update, unable to unlock the damn thing, every solutions failed and had no other choice but to wipe his drive. It’s crazy how bad and unpractical windows can be.
Always wanted to like gnome but never could, and xfce is fine but I much prefer KDE, it is verry likely that I’ll actually keep it till my pc breaks.
