Symptoms
After you remove an application to record CD-ROM / DVD from your computer, you are unable to acces your CD-ROM / DVD drive. It does even not appear in “my computer” anymore !

In “device manager”, the device is marked with a warning sign, and its properties indicate that “Windows could not load the device driver. It might be missing or corrupted (error code 39)”.

This problem is linked to obsolete registry entries that prevent the driver from loading correctly. You need to correct those entries. Both “UpperFilters” and “LowerFilters” registry entries might not appear in your registry. You only need to delete the one that appears in your registry.

In my case, I could only see the “UpperFilter” one, I deleted it and it worked.

1- Start Registry Editor
Click Start, Run, type regedit, and then click OK. Registry Editor starts.

2- Delete the UpperFilters registry entry

1. In Registry Editor, expand My Computer, and then expand KEY_LOCAL_MACHINE.
2. Expand SYSTEM, and then expand CurrentControlSet.
3. Expand Control, and then expand Class.
4. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
5. In the right pane (topic area), click UpperFilters.

Note: An UpperFilters.bak registry entry may also appear. To delete the UpperFilters registry entry, you must click UpperFilters and not UpperFilters.bak.

6. On the Edit menu, click Delete.
7. When you receive the following message, click Yes to confirm the deletion of the UpperFilters registry entry: “Are you sure you want to delete this value?”

The UpperFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.

If a CD recording program no longer works after you restart the computer, you must reinstall the CD recording program.
