As peculiar Windows bugs go, this one is a doozy. It seems Task Manager in the latest October update for Windows 11 (update KB5067036, which is both currently and mercifully optional) is determined to stick around. Like, really determined.
As spotted by Windows Latest on X, if you open Task Manager and then close it down in the usual manner using the "x" button in the top right corner, the Task Manager window will disappear, but Task Manager itself stays running in the background.
