Even closing all applications and windows did not make the Windows Taskbar auto-hide anymore. That’s extremely frustrating for a user who has the taskbar on the left side of the screen. I was not able to maximize windows anymore because the taskbar would overshadow the left part of the screen.

After searching around for some time I discovered a script at Kelly’s Corner that would restore the Windows Taskbar functionality to the default values.

The Windows Taskbar would be reset to its original values by the script and Explorer would be restarted to show the changes immediately. It was moved to the bottom of the screen again but it took only a few seconds to move it back to the left side and enable auto-hide again.

What can I say: The script worked. My Windows Taskbar is auto-hiding again and I did not discover any problems so far with it remaining in the foreground. The script was designed for Windows XP only.
