In Window 7

Clarifications

The Base Versions Home and Basic can not be set the same way as the higher versions.

All you need do in the higher versions is to right click on the desktop and left click on Personalise from the drop down menu and then select Desktop from the next window to open. You then select your preferred picture from wherever you have it stored and go from there.

Thanks for your answer, but I right click on the Desktop, there is no Personalise to select from the drop down menu. I don't know which version.

Doesn't come with the option to change the desktop wallpaper. But there may be third party applications out there that will help, try a Google search for win 7 starter wallpapers.

Irfanview (you can find it via a search) has the ability to set an image file as desktop wallpaper. It works in Win 7 Ultimate, although it may not work for you. Open Irfanview, go to File>Open, find your image, go to Options>Save as Wallpaper, decide how you want it to appear from the choices. Good luck!

1: Open "Computer" on your desktop
2. Click on your hard drive
For this step you will click on your hard drive, and if you are using Windows 7 Starter, your hard drive should only have one partition.
In this case, the hard drive is named Local Disk
3. Open the "Web" folder on your hard drive
This step will require you to open the Web folder created on your hard drive, this will house a folder named Windows. The Windows folder is located on the hard drive. Open these folders.
4. Open the "Wallpaper" folder and replace your wallpaper for good
This step shows you how to replace the wallpaper used by the Windows 7 Basic color scheme. For this you need to open the Wallpaper folder. Inside that folder will be another folder named Windows. Inside that folder is a file called img0. This is your wallpaper. You can replace this image with any other image as long as you make a copy called img0. If you do not copy and rename your image it will not work. The next step will show you how to replace the image.
5. Replace your wallpaper
This is the final step. However, your new wallpaper will not be shown until you log off and log back in to your account.
To do this you need to find the image you wish to replace the wallpaper with. Copy this image. On my computer, I will actually download an image from the Internet. This part is unnecessary unless the picture you want isn't available. Once you have copied the desired image, paste it into the folder you opened back in step 4.
And that's it. You're done.
