Windows Registry Editor Version 5.00

[-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
