Deleting the UpperFilters and LowerFilters registry values is very often the fix for several different hardware problems that generate Device Manager error codes in Windows.

Note: I created this step by step guide to accompany my original How To Delete the UpperFilters and LowerFilters Registry Values how-to guide. There are several very detailed steps in this process, all of which involve the Windows Registry. This visual tutorial should help clarify any confusion and help you feel more comfortable about deleting these items from the registry.

Deleting the UpperFilters and LowerFilters values from the registry should take less than 10 minutes.

To begin, click on the Start button. If you're running Windows XP, click on Start and then Run....

Note: This walkthrough demonstrates this process in Windows 7 but the steps can be followed almost exactly in Windows Vista or Windows XP as well. I'll call out any differences as we proceed through the tutorial.

Important: You might need to reinstall any programs associated with the device you're removing the UpperFilters and LowerFilters values for. For example, if you remove these values for your DVD drive, you may have to reinstall your DVD burning software. This isn't a big issue but I want you to be aware before you continue.
