Disabling Display of Drives in My Computer

This is yet another trick you can play on your geek friend. To
disable the display of local or networked drives when you click My
Computer go to :
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer
Now in the right pane create a new DWORD item and name it
NoDrives. Now modify it's value and set it to 3FFFFFF (Hexadecimal)
Now press F5 to refresh. When you click on My Computer, no drives
will be shown. To enable display of drives in My Computer, simply
delete this DWORD item. It's .reg file is as follows:
REGEDIT4
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersio
n\Policies\Explorer]
"NoDrives"=dword:03ffffff

NOTE:- This is only for your knowledge to know all the features of windows xp . So plz don't do this for illegal things.
