One of the most obvious changes in Windows XP Media Center Edition (XP MCE) 2005, which launches today in California, is the inclusion of a new desktop theme called Energy Blue. Originally, Microsoft intended to include the new theme only with XP MCE 2005; however, the theme is now available for download for Tablet PC users from the Microsoft Web site (see the URL below). I'm also told that if you use a tool such as WinRAR or WinZip, you can extract the downloadable .exe file and use the theme on any XP version. To do so, copy the extracted files to the C:\WINDOWS\Resources\Themes folder. Note that I haven't tried this.
