The one on WindowBlinds actually has the real Vista task bar and it is not recangle. Although, to avoid messing system files, and if you desperaatly want a Vista skin, Get StyleXP with Vista and of course, if you want higher, GET WINDOWS VISTA!
they haven't exactly decided on a release date for vista yet. it just keeps getting pushed back. it SHOULD be released 1st or 2nd quarter of next year. but then again it could be released 3rd quarter of year 3056 so who knows.
I don't think you guys understand the difference between this and windows blinds etc..
Unlike windows blinds and all those other programs, it replaces system files instead of having a binary running constantly in the background. The only processes it adds are Glass2K which is only about 5,500k (Can be disabled) and one for the clock, at a measly 300k. I have disabled both anyhow.
