Microsoft is providing users with plenty of free themes, most of which are designed to work on both Windows 7 and Windows 8 operating systems.
Angry Birds, on the other hand, is not only a very popular game, but also the name of an official Microsoft theme that's addressed to Windows RT tablets too.
Angry Birds comes with a total of 6 different wallpapers, all of which should fit any desktop resolution out there, as long as the computer runs Windows.
Of course, it is offered with a freeware license and takes just a second to install, as all items are packed in a .themepack file that automatically deploys the theme on your computer. Wallpapers are automatically changed at a user-defined interval that can be configured via the personalization screen offered by Windows.
