Have you ever wanted to “theme” XP? Don’t you think that the three “color schemes” that come built in suck? I do. So I have researched things, tried things, and here is what I found.
1) You can pay 30 bux a year to get a program to do it for you. This option is ok, but it is another program running all the time, kinda shakey, crashes, blah blah. The themes are cool, but sometimes hard to get going, installed, etc.
2) You can replace the default version of uxtheme.dll with a hacked one to allow 3rd party themes. This seems like the best bet to me. Finding cool themes is harder though.
Here are some links to get you started:
