Diagnosing and Fixing DVD Drive in Windows that cant read discs & Error Code 39 in Device Manager

We have had this come up a handful of times, so we thought it was a good idea to do a blog about it.

When you have a computer whose DVD drive fails to read a disc, or fails to show up in My Computer, and shows an Error Code 39 in Device Manager, chances are the drive is fine, but there is a Registry corruption related to the optical drive.

Below are the steps for curing that issue once you discover this to be the problem:

1. Open Regedit
2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
3. Scroll down the list, find and click on {4D36E965-E325-11CE-BFC1-08002BE10318}
4. Locate the UpperFilters and LowerFilters values.
5. Right click and delete each, sometimes there is only one or the other.
6. Reboot, your DVD/CD drive should appear in My Computer now, if not you have a different problem.
