Hey guys! I've got a problem here...  
I download the Vista Inspirat 2 Bricopack and when I finished installing it, the appearance is on windows classic style and the windows xp style isn't there anymore!    
The classic style is horrible and I want to change it. Does anyone know how to fix this problem? How do I get it back or can I download one?

Try to patch a file called UxTheme.dll. To patch the UxTheme, download and run the Patcher from:  
for Windows XP SP2: http://www.softpedia.com/get/Deskt [...] inal.shtml
for Windows XP SP3: http://www.softpedia.com/get/Syste [...] -SP3.shtml
 
After patching, reboot, and it should work.

Thanks for the links.
But am I supposed to run the file or replace it with the original one?  
Sorry, I'm not good at this  

 
Run the downloaded file you might have unzip if it's a .zip package.

Nevermind, got it fixed. Thanks for the help
