A free alternative to WBlinds, completely the same so I'm good with it.
SharpEnviro (or SharpE) is an open source shell replacement system for Microsoft Windows XP, Windows Vista and Windows 7. When using SharpEnviro the default Windows desktop is replaced by a new and more powerful desktop environment.
As of december 2011 the SharpEnviro project is no longer under active development. All files provided come without any warranty or support! It is uncertain if or how well the previously released versions of SharpEnviro will work with any new or updated Windows system after Windows 7 Service Pack 1.
