Are you tired of your custom theme, or had pictures up of your pets too long on the desktop? Microsoft has always had awesome free themes for Windows to download. And it recently released a few more of Alaskan, New Zealand, and Swedish landscapes.
You can check out the new themes on the Windows Experience Blog. This is an example of the Alaskan Landscapes theme.
If you want your desktop items to change with themes, make sure to check “Allow themes to change desktop icons” in desktop settings.
