Have you lost your DVD drive or CD Drive within Windows Vista or Windows 7? When you open My Computer the icon for the CD or DVD drive has gone?

We have seen this problem many times, and can be very easily corrected by taking the following steps:-

    If you are prompted for an administrator password or confirmation, type your password, or click Continue.
  2. Locate, and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
  3. In the right pane, right-click UpperFilters, and then click Delete.
  4. Click Yes to confirm the removal of the UpperFilters registry entry.
  5. In the right pane, right-click LowerFilters, and then click Delete.
  6. Click Yes to confirm the removal of the LowerFilters registry entry.
  7. Exit Registry Editor, and then restart the computer.

Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.
