By following these steps, the CD ROM of your windows machine will not be accessible any more (actually not visible). The reasons you may need to disable/enable the CD ROM vary according to your needs (i.e. you don’t want to allow the users of your company to install or run applications via CD/DVD-ROM).
Below you will find the steps you have to follow in order to Disable or Enable the CD/DVD-ROM. You may follow one of the two methods described below:
1 Go to Start > All Programs > Accessories, then right click on Command Prompt and select “Run as administrator”

However, not all editions of Windows has a Group Policy Editor (gpedit.msc). If you’re using a Home edition of Windows, you have to use this registry trick to disable the USB/CD drive access. Here’s how:
1. Press the Windows key + R to open the Run box. Type regedit and hit Enter.
2. In the Registry Editor, navigate to the following key:
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices
If you want to block access to removable devices for ALL Windows accounts, navigate to this key instead:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\RemovableStorageDevices
3. In the left pane, right-click on RemovableStorageDevices, select New -> Key and type in {53f5630d-b6bf-11d0-94f2-00a0c91efb8b}.
{53f5630d-b6bf-11d0-94f2-00a0c91efb8b} is GUID of the generic USB storage device. If you want to block CD/DVD access, type the GUID {53f56308-b6bf-11d0-94f2-00a0c91efb8b} instead.
4. In the right pane, right-click on an empty area and select New -> DWORD (32-bit) Value and type Deny_Read and press Enter, modify its value to 1.
If you want to deny write access, create a new value Deny_Write and set its value to 1.
5. Close the Registry Editor. Restart your computer to apply changes.
To Enable or Disable USB port:
1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK. Or as previously written Press the Windows key + R to open the Run box. Type regedit and hit Enter.
3. Locate, and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
4. In the right pane, double-click Start.
5. In the Value data box, type 3 to Enable and 4 to disable, click Hexadecimal (if it is not already selected), and then click OK.
6. Quit Registry Editor.
To Enable or Disable CD/DVD ROM port:
1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK. Or as previously written Press the Windows key + R to open the Run box. Type regedit and hit Enter.
3. Locate, and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cdrom
4. In the right pane, double-click Start.
5. In the Value data box, type 1 to Enable and 4 to disable, click Hexadecimal (if it is not already selected), and then click OK.
