Developer Stardock has released WindowBlinds 6 today. It is a utility that allows users to customize the look and feel of Windows by applying “skins” to change the user interface of the OS. WindowBlinds 6 can make Windows XP look virtually identical to Windows Vista (including blurred glass). Thanks to hardware acceleration, a typical XP system dressed to look like Vista will perform faster than Vista still. WindowBlinds 6 also adds full skinning support to Windows Vista, making it the first and only program to support full Windows Vista customization. CNet takes a quick look at this new release.
