Last week, I was troubleshooting a PC. The DVD/CD-ROM drive is not able to be seen in windows explorer. In the device manager, the DVD/CD-ROM drives appear with exclamation mark. The user mentioned he has installed the drivers CD from the manufacturer.
- On the Windows Start menu, click Run.
- In the Open box, type Regedit and click OK.
- Select the following key in the Windows registry:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
{4D36E965-E325-11CE-BFC1-08002BE10318} - On the Edit menu, click Delete:
Value Name: LowerFilters
Value Name: UpperFilters - On the Registry menu, click Exit.
- Reboot your computer.
Sometimes, you may find only one of the Value Name. You can continue to delete it and restart your computer.
New: 20/03/2009 or I’m slow. Microsoft posted a new article to fix for Windows Vista.

Thanks so much for posting. It worked.
We had no success after talking to a Dell tech, who thought it was the motherboard. THIS WORKED LIKE A CHARM! Thank you for positing this valuable information!!
GREAT TIP! How did you find this? Wow! Thanks for your help!
Wow, I was at my wits’ end when I came across this post because I’d tried everything I could think of, even a full partition restore but nothing worked. This did! Phew! I’m so grateful, thanks so much for the info.
Thanks! banged my head against a wall for a day…knew it had something to do with the registry, basically because everything else didn’t work! Was about to Ghost this mother…thanks for the 2 minutes solution as opposed to the 4 hr ghost and copy solution
WOW!!!!! This really helped so much. I was so afraid to mess with the registry. I was always told getting in the registry is BAD, BAD, BAD! I was at my wits end and found that Windows support also recommends this (after reading this and searching another couple of days). So, I gave it a shot. I am back and running!! Thanks. — By the way, your directions where so much easier and simple to follow. I just wanted to make sure that I knew deleting these files would be okay.
