Captain: Cloak drives (L, M and Y) in My Computer sector.
Lieutenant: But why captain?
Captain: The program acquires an access to some files on the network; we’ve mapped their folders as drives within My Computer. Now we don’t want the user to realize their existence, even if they do…they might mistake it with the local drives, and decide to work in it.

  • Note: you can use the next tip for both local and mapped drives, however, it will not prevent the access to the hidden drives
  • (If you hide the C drive, then Open explorer and type c: and it will still take you there)

    1) From (Start) click on (Run), type (regedit).
    2) Browse to (HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer).
    3) Right click on the side panel choose (new) and (DWORD value) name it (NoDrives) key sensitive.

    Now here is the big deal:
    A 00 00 00 01
    B 00 00 00 02
    C 00 00 00 04
    D 00 00 00 08
    E 00 00 00 16
    F 00 00 00 32
    G 00 00 00 64
    H 00 00 00 128
    I 00 00 01 00
    J 00 00 02 00
    K 00 00 04 00
    L 00 00 08 00
    M 00 00 16 00
    N 00 00 32 00
    O 00 00 64 00
    P 00 00 128 00
    Q 00 01 00 00
    R 00 02 00 00
    S 00 04 00 00
    T 00 08 00 00
    U 00 16 00 00
    V 00 32 00 00
    W 00 64 00 00
    X 00 128 00 00
    Y 01 00 00 00
    Z 02 00 00 00

    Note that every eight drives are related to the same column -every column is separated by spaces- counting from left to right (I to P belong to the second column).

    4) You’ll need windows calculator for this thing, From (Start) click on (Run), type (calc). From (View) choose (Scientific).
    5) You need to calculate each column drives you wanna hide, with (Dec) selected add the numbers of the same column in the calculator then hit the (Hex).
    6) Line all the columns’ calculations in one line without spaces

  • Example: Hide (C, H, M, O and Z): 02005084
    C+H= 4+128= 132 (Hex it 84).
    M+O= 16+64= 80 (Hex it 50).
    No drive is hidden from third column=00 (Hex it 00).
    z=02 (Hex it 02).
  • To hide all drives (03FFFFFF), to show them all delete the value (reset it to 0)

    7) Restart your PC to apply changes.
