Tired of using the same wallpaper but tired of having to constantly change your wallpapers…..?
Windows 7 has a solution……..
The much easiest way is to select multiple images in an explorer shell anywhere, right clicking and choosing Set as Background. Windows will automatically cycle through the chosen images.
If you are itching for a little more control, right click anywhere on the desktop,
Choose Personalize >> Desktop Background and Choose multiple images. You can now choose the interval between changes as well as the order in which they are shown.
