Xteq X-Setup is a so-called "Hacker" program. It allows you to change settings that are normally hide deeply in some configuration-files (like the registry) fast and easily.
By using X-Setup you do not need to use REGEDIT.EXE or search for some INI files where you can change these hidden features, you simply use X-Setup, tell it what you want to do and it does the rest.
One of the major features X-Setup has, is that is allows you to choose between two modes: Plug-in Mode and Wizard Mode. In Plug-in mode you use a hierarchical display to navigate to the settings you want to change. In Wizard Mode, you simply select a topic you are interested in from the "Wizards" menu and X-Setup will display a Wizard that allows you to change the settings in a step-by-step process.
Because many of this features change quickly (with every new versions of a program or Windows), Xteq X-Setup uses plug-ins (See What are plug-ins? for more information). X-Setup comes with a lot of plug-ins and of course Xteq Systems will make more plug-ins available.
