Updates an issue for a small number of users that prevents the Start menu from working and prevents you from seeing the updated taskbar after upgrading to Windows 11 (original release).

Just like Windows 10, Windows 11 will be serviced with monthly updates, and Microsoft will ship “B” releases on the second Tuesday of every month followed by optional “C” releases later in the month.
