Hide Drives in My Computer (Current User) (All Windows)

This setting allows you to control which drives are visible in My Computer and Explorer. It is possible to hide all drives or just selected ones.

Open your registry and find or create the key below.

The "NoViewOnDrive" value uses a 32-bit bitmask to define local and network drive access 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.
