X-Setup is one of the better "tweaking" programs we've ever reviewed -- and it's free. You can use one of two modes to easily change hundreds of hidden settings -- not only for Windows 9x and NT, but for many popular programs and games. Plug-in mode provides an Explorer-like hierarchical display so you can navigate to the settings you want to change. In Wizard mode, just pick a topic of interest from the Wizards menu; X-Setup runs the appropriate wizard to help you change the settings in a step-by-step process. You can even change the colors of the "Blue Screen of Death." Since software and hardware change so quickly, X-Setup can be updated with new plug-ins to keep up with technology. Instead of hacking through the Registry and .ini files like a common geek, go first class with X-Setup.
