May not be completly legal here, but there is a free way of altering colors/look of Windows, it turns off the uxtheme certifying check to allow custom themes. These themes can be found at deviantart.com.
Microsoft made a black and Orange theme for XP for the Zune, there's a link to the free download. Don't worry, it has nothing to do with the Zune but the colors.
If you patch uxtheme.dll you can use any style you want. Here is some software that will do it for you.. Multi-patcher 5 Pretty sure its legal, I don't think softpedia would have posted it if it wasn't..
There are also guides and a few other programs if you Google something like 'patch uxtheme'
nice theme thanks alot for this but strange is that i cant find it over the regular download page. Besides, are there any other themes? XPEnergyBlue is already installed
