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” 1

reg add HKLM\System\CurrentControlSet\Services\cdrom /t REG_DWORD /v "Start" /d 1 /f

To Disable CD/DVD-Rom:

reg add HKLM\System\CurrentControlSet\Services\cdrom /t REG_DWORD /v "Start" /d 4 /f
