Tech Software:
The DVD Drive is not recognized by Windows Device Manager

This article discusses a Windows registry fix to make your PC see a connected DVD drive that isn’t otherwise being detected by the operating system.


I have seen this snafu occur on many of my "fix my computer" appointments. I am not even aware of what causes it to happen in the first place. The first thing customers think is they should go out and purchase a new DVD drive. This usually doesn’t really solve anything, because the glitch can happen again with any DVD drive.

This is an issue with the Windows system registry. Some erroneous registry key entries have been added which are blocking Windows from acknowledging the existence of a physically connected DVD drive. These bad registry keys need to be manually removed from the system registry using the “regedit” registry editor. Here is a solution for this problem which I have used successfully in my software business.

  1. Click the Start button in the lower left corner of the screen.
  2. In the Start Search box type regedit for Windows Vista and Windows 7. For Windows XP, click the Run item on the Windows popup menu and then type regedit in the box that appears.
  3. Find and click the following system registry key: HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}. You need to verify that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
  4. In the right pane, if you have UpperFilters, right-click UpperFilters, and then click Delete.
  5. Click Yes to confirm the removal of the UpperFilters registry entry.
  6. In the right pane, if you have LowerFilters, right-click LowerFilters, and then click Delete.
  7. Click Yes to confirm the removal of the LowerFilters registry entry.
  8. Exit Registry Editor, and then restart the computer.

These instructions may seem intimidating at first to someone who has never done a computer repair to modify the Windows system registry. It really isn’t that hard once you get used to moving around inside the registry editor. In fact, it is probably a good idea to get used to navigating your way around the Windows “regedit”. There will probably be other issues that arise where you need to modify the registry to correct a registry related problem caused by any number of other issues. Above all else, you need to be careful not modify or delete registry key entries that could create new problems with the Windows operating system.
