Microsoft is celebrating its 5th anniversary with a free for Windows. The theme pack consists of 13 high-resolution images featuring the animals, landmarks, and eye popping scenery that have made its way to the Bing home page over the site’s first five years.
This time Microsoft has packed it in a executable file instead of regular .themepack package, probably to promote Bing, as the executable gives you an option to set Bing as home page or default search provider. Then it automatically applies the theme and launches the personalization gallery where the themes get populated. Moreover this theme is compatible with Windows 8.1, Windows 8, Windows 7, Windows Vista, and Windows XP.
