how to open dvd rom with cmd

You can hide the drive by tweaking Windows Registry, so that no one can see the specified drive.

Go to Start -> Run and type Regedit to start the registry editor. Now you need to follow a specific key which must be edited:

HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Policies / Explorer

Right click in the right panel and select New->DWORD value. Name it NoDrives. You will immediately observe that this new DWORD value got its data something like this: 0x00000000. The 0x in the front of the value means the number is stored hexadecimal (base 16). There are four sets of double 0. This means that every set has its representations as follows (from right to left):

- first set: drive letters from A to H
- second set: I to P
- third set: Q to X
- fourth set: Y to Z

The value number for the each drive is:

1 for A I Q Y, 2 for B J R Z, 4 for K C S, 8 for D L T, 16 for E M U, 32 for F N V, 64 for G O V and 80 for H P X.

Now focus on the information I provided you with above. If you want to hide partition E:, you should edit the NoDrives value as follows: E: corresponds to the first set of double 00 and the value for E is 16. Therefore, replace the first (rightmost) double 00 with 10 (the hexadecimal representation of the number 16).
