Anybody who has ever tried to change the theme in Windows will already know that you have to hack the uxtheme file in order to install themes into XP that aren’t digitally signed by Microsoft. If you would rather not or are unable to patch your system you might be interested in these unofficial themes created by Microsoft.
There might be other themes out there, but these are the ones I know about. Feel free to inform everybody in the comments if you know of any others.
This theme is really bright and blue… Just look at all that blue…
To install this theme you’ll need to download, extract the zipfile, and then run the installer. When prompted for the location to save the files, leave it set to default.
Now you can go into your display settings and change the theme from the list.
This theme was supposed to be a darker version of the regular Royale theme, but it wasn’t really finished before somebody from Microsoft published it, and it spread all over the web.
After downloading and extracting the zipfile, you’ll need to copy the royale_noir folder into C:\Windows\Resources\Themes and then double-click on the Luna.msstyles file found in that directory and change the settings to match the above screenshot.
This theme was released to celebrate the Zune launch, and you’ll notice it’s very similar to Royale Noir, except for the kinda ugly orange start button. Long time readers will note that we’ve mentioned this theme before.
Installing this theme is really simple… download and run the installer.
