LiteStep was originally written a few years back by LoneRunnr, who didn't want to do things "the Microsoft way". After some time he stopped working on the project and opened the source up under the General Public License.
Once LiteStep was released, the project was picked up by some programmers, who have made it to the software you have downloaded today. The LiteStep Development Team has gone through many changes since its creation. The application concept, however, is still the same: the main idea is to allow users to control the look, feel and even functioning of their Windows GUI in any manner they want - not something you can easily say about the Microsoft Explorer shell.
This major leap in beauty and functionality does not come without a price however. LiteStep users must be comfortable with text based configuration and have to accept the fact that Windows will not operate like they were used to (which is not necessarily a bad thing).
