SYMPTOMS

You upgrade a computer to Windows Vista or you install or uninstall applications that have a CD/DVD filter driver. When you restart the computer, the CD drive or the DVD drive no longer works as expected.

CAUSE

This problem may occur if one of the following scenarios is true:

  • The filter drivers in the CD and the DVD storage stack are not migrated successfully to Windows Vista.
  • You uninstalled CD software that fails to properly remove itself in the registry.
  • You installed software that adds filter drivers in the CD and the DVD storage stack that interfere with existing filters.


RESOLUTION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, remove the affected filter drivers. To do this, follow these steps:

  1. Click Start[GRAPHIC: Start button], type regedit in the Start Search box, and then click regedit in the Programs list.

    [GRAPHIC: User Account Control permission ] If you are prompted for an administrator password or confirmation, type your password, or click Continue.
  2. Locate, and then click the following registry subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

    Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
  3. In the right pane, right-click UpperFilters, and then click Delete.
  4. Click Yes to confirm the removal of the UpperFilters registry entry.
  5. In the right pane, right-click LowerFilters, and then click Delete.
  6. Click Yes to confirm the removal of the LowerFilters registry entry.
  7. Exit Registry Editor, and then restart the computer.

Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.
