Few Days back one of my friend got a new HP notebook, was much excited to use Window 7 Starter which came wid it. But later he came to know dat Window 7 Starter does not facilitate changing Desktop Background, then he googled it out and found the solution which m goin to share wid u all.

There's an application named Oceanis Change Background Windows 7 provided by Oceanis so that you can change the desktop background with a optional desktop slideshow (shuffle) in the Windows 7 Starter and Home Basic editions.
Steps:

1. Download the Oceanis Change Background Windows 7 ZIP file below provided by Oceanis, click on Save, and save it to your Desktop.
Download (3.17 MB)

2. Extract Oceanis Change Background Window 7.zip
3. Run the Oceanis_Change_Background_W7.exe file
4. You might be prompted to restart ur system to complete the installation
5. When your computer restarts, you will see this as your desktop background. Click on the Oceanis Change Background Windows 7 shortcut to change your desktop background. (see screenshot below)


6. Browse to the images that you want to use and check (select) a image, or more than one image to have a desktop slideshow. Select the Picture position for how you want the images displayed, and any desktop slideshow settings if you selected more than one image. (see screenshots below)

If you ever do a in-place upgrade to another higher level edition of Windows 7 in the future, then be sure to uninstall this Oceanis Change Background Windows 7 program first to avoid incompatibility issues with it in the new edition of Windows 7. It was designed to only work in the Windows 7 Starter and Home Basic editions.
