Yellow exclamation mark in DVD/CD-ROM drives in Device Manager
Nov 08
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.

Sorry ment to say “does NOT work for me”

it is very usefull thanx for help
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.
