Locking CD-ROM Drives

(For Windows 2000, XP and NT)
      Similar to the above example, it is also possible to lock access to the CD-ROM drive by the following steps:

1. Open the regedit.exe file.
2. Search for the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT  \CurrentVersion\Winlogon
3. Create a new string entry named AllocateCDRoms and set its data value to 1 to ensure that only the  local   logged on user can access the CD-ROM drive. On the other hand, if the string entry's    data value is set to 0 then all restrictions are lifted.
4. Exit the Windows registry. You might have to restart the Windows session for the changes to come into effect.

   
         It is also possible to implement the above by simply creating    and executing a file with a .reg extension containing the    undermentioned data:

REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon]
"AllocateCDRoms"="1"
