While Win11's update seems to work normally, Win10's was broken for me on every copy of Win10 so far. The update window or dialog shows the usual cumulative & malicious software removal updates, but once the updating starts, everything disappears. It's only by watching Task Mgr. that I can see the update is still being performed, though the restart button usually appears once it's completed -- one copy only showed update & restart where you'd normally see restart, shutdown etc., & when clicked restarted into a setup-like mode before restarting again into the normal screen showing update progress.
