I got the same problem here on my XP SP2 machine, my virtual Vista install has the same problem :/ Edit: Nice, I found a way to make it work You have to copy the WAIKX86.MSI (or the 64bit version) and the WINPE.CAB to your HD. Then run the MSI. Thats it
I think it's XPreviews problem, I've changed the colors an tested it with virtual pc and the colors were changed. So don't worry, the colors are changed right, it's just a bit more complicated to test it...
