How to hide partitions using registry editor

Partitions on a Windows machine can be hidden using the registry editor. Applications and the command prompt will still have access to it, and you can still manually browse to the folder by typing the path.

Go to Run and type in: regedit

Press Enter and if UAC (Universal Access Control) prompts, click Yes

Locate the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
If the Explorer key does not exist, right-click on Policies, select New Key and name it Explorer.

Now right-click and create a new 32-bit DWORD and name it NoDrives.

This value is a 32 bit number, and the bits are arranged in reverse order with a value of 1 hiding that drive. For example, if we wanted to hide drive E and Z, we would arrange it like this:

 

If we convert the binary 10000000000000000000010000 to hexadecimal, we will 2000010.The decimal value would be 33554448.

Press ok and restart explorer/computer for the changes to take effect.
