Problem: You try to play a DVD movie or try to run some other disc and nothing happens. The drive spins and seems to work but Windows does nothing. You look into My Computer and the drive is missing there. You look into the device manager and see the device but it has a warning.
Fix: You need to delete the optical drive upper/lower filters entries in the HKLM registry tree.
THE METHOD:
- Open RegEdit (Start>Run> Type “regedit”)
- Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}”
- Delete the “UpperFilters” value.
- Delete the “LowerFilters” value.
- Restart the computer.
- You might need to uninstall then reinstall any burning software you may have (Nero, iTunes, etc…) do this now.
Note: Backup your registry and create a restore point before doing any of this.
How to explain this problem to the client: Sir, sometimes when you uninstall a burning application it forgets to change a few settings so that other programs will work fine. This is just a case where it forgot to remove its’ “upper/lower filters” settings. No worries though your computer is now safe and sound! Money please.
Good luck and tell me how it goes on the forums.
