I hope it's not too late to post this but I've been swamped - I had a few Christmas Windows XP themes archived that I want to share just barely in time for the holidays. Microsoft won't let you use any third-party themes unless you patch your uxtheme.dll. The latest version of UXTheme Multi Patcher can be downloaded from: https://www.windowsxlive.net/uxtheme-multi-patcher/ Scroll all the way to the bottom and click the download link. Unzip and run Make sure you untick the 'Set Windows X's Live as default homepage' box and hit 'Patch'. Wait a bit while it modifies the .dll file. Now you can use third party themes! I have 3 you can download in 1 zip file: https://www.mediafire.com/file/21nvwrdibgxklde/ChristmasThemes.zip/file Extract to \WINDOWS\Resources\Themes Use Explorer and navigate to one of the folders you extracted and click on the .msstyles file. Just click 'OK' and you have a festive theme! Happy Holidays!

I've re-uploaded the Christmas themes for XP for new members to this forum since the previous links have expired. https://www.mediafire.com/file/4vaafnljdwofnwt/ChristmasThemesXP.zip/file XP has the most customizable GUI of any Windows versions. Changing color schemes/wallpaper is not the same as having the ability to customize the controls/backgrounds for the entire interface. There used to be a site (stylexp.org) that had the tools for creating your own XP themes but they are defunct.
