If you have it installed on a desktop computer, you probably don't have this problem, but if your version of Windows 7 is called Starter, you've already noticed that you can't change your desktop background.

With this free program you solve this problem simply by installing Oceanis Change Background Windows and restarting your computer.
You don't have to worry about the consumption, because it hardly uses memory and it doesn't alter the operation of your Windows either.
