How to Disable Drives in My Computer from unknown user

Security of your data is the most important thing for every person, what would be the security of data in a computer which have multiple users on the PC in your home. Every user have access to every bit in the computer and hence computer had never been personal unless its exclusively used by you alone Lets tweak the computer to disable drives where you can keep all those valuables and hide it from the external users. That's only you, who can handle the data even in a shared computer.

If you want to prevent all users who want access to your computer or network shared drives on the workstation, then you can hide the all drives as C: /, D: /, E:/,  and save your data from any unknown user. But the next time you can turn on the display of these drives with the Registry Editor. Now edit the computer registry to turn off the display of drives.

Follow the given steps below

First Click Start Button > Click Run.

Go to Run box and type regedit hit Enter Key

Then locate the following key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

In the right side pane, create a new DWORD value name it disabledrives then Double click the value,

click on Decimal for the Base Unit.

For specific drive use values (For example: for A, B, C, D, E, F, G, H drives, the values are 1, 2, 4, 8, 16, 32, 64, and 128 respectively)

A = 1

B = 2

C = 4

D = 8

E = 16

F = 32

G = 64

H = 128

In this case we are trying to hide C drive, so we modify the value data box to 4 or to hide F drive, we modify the value data box to 32.

Now if you want to hide all the system drives then modify value data to 3FFFFFF.

Set it to the DWORD Value 3FFFFFF (Hexadecimal)

You can also hide multiple drives by adding the numbers of the particular drives simultaneously ( For example: if you want to hide drive C and drive G, you would type in number 68, which is 4+64)

Close the Registry Editor.

You'll need to reboot your computer before the changes take effect.


When you want to get your drives back, change the value of disableDrives to 0 or simply delete the value or delete the whole DWORD item.

Note:- This trick also work in Vista Home Edition.

That's all.
