Free tweak software for windows

Its highly customizeable through the implemented IE engine -- supports native IE features: HTML, xHTML, XML, CSS, JScipt, VBScript, ActiveX, etc. In contrast to hundreds of so called tweakers, Tweak FX uses plugins, that can extend its possibilites to a significant range. All plugins are simple HTML pages and you can modify them to meet your needs.

- build-in Web browser based on the Internet Explorer engine
- tracks all changes made by a plugin and can export them as a standart Windows Registry Editor Entries (.reg file) # up to now includes more than 50 plugins
- provides some libraries which can be used through the ActiveX interface # absolutely freeware!
