CD Drive Disappeared

Several of my customers have had their Optical Drive (CD/DVD) disappear from their My Computer after uninstalling or installing a program. It can also be caused by some virii so be aware.

Most of the time, its old left-over registry entries by the programs that remain after removal that cause the problem.

To fix this follow these steps:

1. Go to Start button (lower left hand corner), go to RUN, type REGEDIT
2. Navigate to
   1. HKEY_LOCAL_MACHINE\
   2. SYSTEM\
   3. ControlSet001\
   4. Control\
   5. Class\
   6. {4D36E965-E325-11CE-BFC1-08002BE10318}
3. Delete the UpperFilters and LowerFilters Keys.

Restart your system and you should see the drive. You may be prompted to reinstall it upon start-up.
