    i tried to do the things that you did above and when i run the batch file with “run as admin” it pops up a cmd windows very quickly and then close. i dont know if that was normal.

    and when i try to view the windows update. i can see the 3 updates at the “installed updates” and they are already installed without my permission. @_@
