Disable/Remove the Taskbar
The following script saved as removeTaskbar.reg will remove all of the items individually, forcing them not to show up on the desktop.
REGEDIT4
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects2]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoSetTaskbar"=dword:00000001
"NoTrayItemsDisplay"=dword:00000001
"HideClock"=dword:00000001
"NoToolbarsOnTaskbar"=dword:00000001
"NoTrayContextMenu"=dword:00000001
"NoSaveSettings"=dword:00000000
*NOTE if you wish to have this only applied until your next reboot, run this with:
"NoSaveSettings"=dword:00000001 instead.
this will keep windows from saving these settings, and the taskbar should reappear on your next reboot
**If it doesn't, change all the values to 000000 to disable ALL features, also remove the - from the first path line. This will return the taskbar and it's components.
*NOTE you may have to re-add any toolbars, etc you had previously added to the taskbar.
