This post reviews the most popular free for download themes for Windows.

Themes for Windows XP often requires different types of heavy and resource demanding 3rd party software, e.g. like ThemeXP and others. In this post I have collected the most popular themes that do not require additional 3rd party software.

The Luna Theme The Luna Windows XP theme is the traditional Windows XP theme. The Luna theme aka the official Windows XP Style is available in three different color schemes; Blue (the default), Olive Green, and Silver.

The Energy Blue Theme The Energy Blue theme is a theme concept produced by Microsoft and introduced in 2004 for the Windows Media Center and Windows XP Tablet editions. It is composed of a new redesigned wallpaper (inspired by Windows XP Bliss) and a new desktop theme and skin. The concept presents aesthetic brilliant and relucent blue and green colors. The Energy Blue theme is not only available for Windows Media Center and Windows XP Tablet editions, but also regular Windows XP editions.

The Royale Themes The Royale theme is a new theme for Windows XP that has leaked out of Microsoft and onto the web. The theme appears to have come out of a beta version of Windows Media Center 2005 that was in testing. The Royale theme is an aesthetic theme and comes with two color schemes Royale (a blue theme) and Royale Noir (a black theme). The Royale theme is refreshingly different to the traditional Windows XP Luna theme.

The Zune Theme After the Royale and the Royale Noir themes were leaked onto the web Microsoft decided to release a modified version of the Royale theme called Zune - perhaps to promote the release of their new invention - the Zune. The Zune theme is different to the Royale and the Royale Noir themes by having orange controls and a orange start-button.

Matching Firefox Themes Until now I have been unable to find matching themes for Mozilla Firefox. I'm currently searching the net for a Firefox theme that matches the Royale Noir theme.
