Standard Disclaimer:

Using the Windows Registry Editor incorrectly can cause serious problems requiring the re-installation of your operating system and possible loss of data. I do not and will not support problems that arise from editing your registry. Use the Registry Editor and my directions at your own risk. Be sure to create a backup and be sure that you know how to restore it. If you can not do both of these things then STOP here!! and read the directions.
