Fix DVD/CD Drive Problems By Removing Upper/Lower Filters
Last Updated 2 years ago

When your DVD/CD drive doesn't read or write any of your compact disks, device drivers are primarily needed to get updated. However, this is not mostly the case. Upper or lower filters are sometimes added in your registry, which causes the problem.

To fix your DVD/CD drive, try removing the upper and lower filters in the registry:

Step 1. Create a restore point and back-up your files.

To create a restore point, please refer to this article "How to Use the System Restore Point".

Step 2. Access Registry Editor.

  1. Open the Run window.

    • For Windows XP: Click the Windows Start button and select Run.


    • For Windows Vista and 7: Click the Windows Start button > All Programs > Accessories > Run.


    • For Windows 8, 8.1 and 10: Right-click the Windows Start button and select Run.


  2. Type regedit, then click the OK button.


Step 3. Remove UpperFilters and LowerFilters values.

  1. In the Registry Editor window, expand the:

    • HKEY_LOCAL_MACHINE key by double clicking it (or clicking the "+" next to it.)

    • System key

    • CurrentControlSet key

    • Control key

    • Class key


  2. Select the {4D36E965-E325-11CE-BFC1-08002BE10318} key.
