Upper and lower filters

    Question

  • In order for me to delete upper and lower filters I first have to know what they are.  Can someone explain to me before I make a big mistake!  Thanks!

  • UpperFilters and LowerFilters values, sometimes incorrectly called "upper and lower filters," might exist for several device classes in the registry, but those values in the DVD/CD-ROM Drives class tend to corrupt and cause problems most often.
    If you're in trouble with the CD/DVD unit, read the Microsoft Knowledge Base article that you find at the following address
