This is a great trick you can play on your friends. To disable the display of local or networked drives when you open My Computer.
1. Go to Start Menu -> Run, and then type regedit and press enter
2. Go to HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
3. Now in the right pane, create a new DWORD item (By clicking Edit on the Menu Bar and then selecting New -> DWORD Value) and name it NoDrives (it is case sensitive).
4. Now Double Click on it and set its value to 3FFFFFF (Hexadecimal).
5. Reboot your PC
After restarting, when you open My Computer, no drives will be shown (all gone...).
To enable display of drives in My Computer, simply delete this DWORD item that you created. Again restart your computer. You can now see all the drives again.
