Hi Vernon,
As I mention in my instructions,
Please save your registry before you make these changes. To do so, type in start menu ''regedit''. Select file and export. (Name the file Full registry around 35 megs). You may also write down original settings and reset.
before you do this (which BTW is 99.9% safe) you can export your registry.
In search of start menu, type regedit and press enter. In the registry, select file/Export. This will export your original registry as a .reg file.
Save it to a location that you can easily find it and namre it simply Registry.reg.
If for some reason, you wish to return to your default settings, simply go to that .reg file/double clic on the registry.reg file and accept instructions on the screen.
That's it.
