Task Manager stops showing tasks, widespread install failures

The October preview update for Windows 11 24H2 broke Task Manager — the one tool every Windows user reaches for when something goes wrong. After installing KB5044384, Task Manager stopped displaying running tasks entirely, making process management impossible. You couldn’t see what was running, couldn’t end hung processes, couldn’t monitor resource usage. Installations failed left and right too, stalling at 90-95% with errors 0x800f0922 and 0xc015001a. Microsoft advised waiting for November’s Patch Tuesday, which is one way to handle breaking the tool people use to diagnose your broken updates.
