The suggested solution calls for editing the registry.
While editing the registry gives you access to a wealth of options that may not be offered to you through the user interface, it also gives you the means to completely mess up your system in the time it takes to reboot. As a precautionary measure, since things go wrong every day...any user considering editing the registry...should first back up the registry for possible future use.
A manual backup creates a file of your registry information, which can be stored until needed, and restored to roll your registry back to a stable state in case of disaster. This also gives you the added security of being able to store the backup on removable media such as a floppy or CD to be kept until needed.
An excellent program for doing such is ERUNT Registry Backup Tool - http://www.snapfiles.com/get/erunt.html
