deny Drives using registry

Step 1 : Run -------> type regedit.msc 

Step 2 : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies

Step 3: create a DWORD value named   NoDrives

step 4 :   Set value 1 to enacle 0 to desable

The "NoDrives" value uses a 32-bit word to define local and network drive visibility for each logical drive in the computer. The lower 26 bits of the 32-bit word correspond to drive letters A through Z. Drives are visible when set to 0 and hidden when set to 1.

If your not happy working in Hex, add these decimal numbers to hide the drive(s):

A: 1, B: 2, C: 4, D: 8, E: 16, F: 32, G: 64, H: 128, I: 256, J: 512, K: 1024, L: 2048, M: 4096, N: 8192, O: 16384, P: 32768, Q: 65536, R: 131072, S: 262144, T: 524288, U: 1048576, V: 2097152, W: 4194304, X: 8388608, Y: 16777216, Z: 33554432, ALL: 67108863

For example to hide drive A and drive D, you would add 1 (A) + 8 (D) which means the value should be set to "9".

To disable all the drives set the value to "67108863".

Restart Windows for the change to take effect.

Note: These drives will still appear in File Manager, to remove File Manager, delete or rename winfile.exe.
