Geez, some people are of no help sometimes. hake:
You need to get a program called [url=http://www.tgtsoft.com/prod_sxp.asp:cfcd2]Style XP[/url:cfcd2]
You can then get XP themes from various websites. I would recommend
http://www.themexp.org
Then install the themes (Sorry, I haven't done it for a while, I forgot. The Zips that the themes come in usually have a ReadMe)
Hope that helps. There are other sites for themes, I just can't think of any off the top of my head. freak:
