TIMED Shutdown

[raznehb]

This works with all Windows 95/98/NT4/2000/ME/XP/2003 releases.

To prevent a drive or any combination of drives from appearing in My Computer, Windows Explorer and/or Internet Explorer, for security purposes in a multiuser environment, if you own the computer or have Administrator privileges, add/modify the "NoDrives" (don't type the quotation marks) Binary [REG_BINARY] hex or DWORD [REG_DWORD] value under this
Registry key, using Regedit:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
Give it a value from the list below to hide the individual drive(s) of your choice (don't type the spaces for Binary):
Drive Letter     Binary Value     DWORD Value

A   01 00 00 00   00000001
B   02 00 00 00   00000002
C   04 00 00 00   00000004
D   08 00 00 00   00000008
E   10 00 00 00   00000010
F   20 00 00 00   00000020
G   40 00 00 00   00000040
H   80 00 00 00   00000080
I   00 01 00 00   00000100
J   00 02 00 00   00000200
K   00 04 00 00   00000400
L   00 08 00 00   00000800
M   00 10 00 00   00001000
N   00 20 00 00   00002000
O   00 40 00 00   00004000
P   00 80 00 00   00008000
Q   00 00 01 00   00010000
R   00 00 02 00   00020000
S   00 00 04 00   00040000
T   00 00 08 00   00080000
U   00 00 10 00   00100000
V   00 00 20 00   00200000
W   00 00 40 00   00400000
X   00 00 80 00   00800000
Y   00 00 00 01   01000000
Z   00 00 00 02   02000000

Example: to hide drives D, E, Y and Z give "NoDrives" this Binary value:
18 00 00 03
Where: D + E = 18 and Y + Z = 03 (cumulative values).
NOTE: These numbers are in HEXadecimal. Example: to hide drives A, B, C and D, use 0F, NOT 15, when cumulating multiple drives.
Show all drives (A to Z) "NoDrives" Binary value:
00 00 00 00
Hide all drives (A to Z) "NoDrives" Binary value:
ff ff ff 03
You can also do this by using TweakUI, one of the Microsoft Power Toys for Windows 9x/NT4/2000/ME + MS IE 4/5/6 [110 KB, free, unsupported].
Use TweakUI with caution, ONLY AFTER BACKING UP YOUR REGISTRY!
Open Control Panel -> TweakUI -> My Computer tab -> check to show or uncheck to hide the desired drive boxes -> click OK/Apply.
Windows default is to show ALL local and remote (network) drives: A to Z.
