Energy Blue Theme for Tablet PCs can also work in any version of XP

Microsoft released a new theme for Windows Media Centre PCs just launched but have also included it for the few people that have tablet PCs, its called "Energy Blue"

Tablet PC Energy Blue Theme

If you download the theme it can be used in standard windows XP too with a little extraction and copy/paste.

Use a tool such as WinRAR or WinZip or my personal open source freeware favourite 7-Zip, you can extract the downloadable .exe file and copy the extracted files to the C:\WINDOWS\Resources\Themes folder.

Then right click your desktop and choose "Energy Blue" from the Themes tab and click apply.
