[Shadowblitz16]

Does anybody know a good windows theme making tool?
I want to do a complete resin of my computer
like..
custom ui sprites
custom overlay sprites
custom bar sprites
custom colors

basically a complete reskin of win7
I have found this program however it doesn't seem to work properly(has ton of bugs?)
and I don't really trust it to buy it online

Edit: also did I mention I would like to use it in a visual studio form application too

I personally use Ave's Windows7 Style Builder it is not free it is $27.53 US after purchasing you can join their forum at VistaStyleBuilder - Index you need your email address and license key to join and there is excellent help there with maps showing the different locations.
