Problem description:

  • After you remove a program from your computer, or you update the firmware of your optical disc drive, you can no longer access the CD drive or the DVD drive successfully, or the drive does not appear in "My Computer" anymore.  
  • You receive an error message when you try to access the drive.  
  • In Device Manager, the optical drive properties shows a random error code.

This article contains two methods to resolve this problem. One of the methods requires that you manually modify the Windows registry to remove the UpperFilters registry entry and the LowerFilters registry entry. You must restart the computer after you follow the steps in this article.

Solution 1: use Microsoft Fix it to delete the registry entries


Note: We recommend that you uninstall all CD recording or CD writing programs before you delete the registry entries. You can reinstall any programs that you use after you resolve this problem.
Microsoft Fix it is available to delete the registry entries that can cause CD access problems. Microsoft Fix it can automatically perform the steps for you.

The actions that this Microsoft Fix it performs can be undone after Microsoft Fix it is finished. If you would like to undo it, run Microsoft Fix it again.

Method 2: Manually delete the registry entries

Important: This method contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully.
For added protection, back up the registry before you modify it, so that you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, you can consult the relevant article in the Microsoft Knowledge Base

Additional note about Optical Disc Drive drivers

An optical disc drive always uses Windows drivers.  For this reason, you will never find a driver update for your DVD or Blu-ray drive in our downloads section.
If, for some reason, you want to reinstall the drivers of your drive, you can just uninstall it from Device Manager, and have Windows check for new hardware.
