Stop root shares

On Windows XP (and other), the C:, D:, and E: disks are silently shared on the network.

If no password has been set on the user, then only the username is required to gain access.

For example, anyone on the local network may visit \\yourcomputername\c$ and access
the contents of the whole C-disk just by typing in your username.

To avoid this, turn of "administrative shares".

Make a file named whatever.reg, put the following into it and then double click on the file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters]
"AutoShareWks"=dword:00000000


(Make sure the file ends in .REG and not .TXT.)
