Custom themes on Win7

Hey, sorry for making a new thread, I'm sure that this isn't the first one made here but, I couldn't find any.

So, I want to use custom themes on my Win7 (7100 version) and I found a tutorial with three .dll files, the problem is that I can't replace the files in my System32 folder.

The files I'd need to update is shsvcs.dll, themeui.dll and uxtheme.dll.
If any of you guys have any better way to use custom msstyles, please tell me or link or stuff : )

thanks in advance.

try this, i've used it with success on 7100 and 7229.

umm does this mean I can use the same themes that I could use on win xp? from customize.org or sites? 'Cause I patched the files, booted but dunno how to get the themes up and run : <

where can those be found?

well since there is no app to help people make themes yet, they must be done with resource hackers, so themes are not yet prevalent. look around deviantART in the section for Vista Visual Styles and you'll find a handful. nothing to shout about yet.

the best one is called AeroPlain. it's the best 'cause i made it
