Desktop wallpaper is an image which resides on your background screen and adds colour to your computer. It is visible when all the windows are minimized and there is no application running in maximised state. Wallpaper defining and customizing has been a part of all the graphical version of Microsoft operating systems right from Windows 95, which has now  been taken to another step with Windows 7. In Windows 7 you can select multiple pictures or wallpapers and can set a timeout for them so that they change by themselves. This feature of Windows is called as Windows Wallpaper Slideshow. In this post we will discuss the way of how to use this feature and how to make the wallpaper change after a fixed time.

To use this feature all the steps are quite same as in Windows Vista but the multi select feature is added to it. Lets us start the process by Minimizing all the open Windows (if any) any and then Right Clicking anywhere on the desktop and selecting Personalize from the context menu. Once the Personalize Window is open click on the “Desktop Background” link and then you will see the Desktop Background window. If you have a folder in which you have the pictures which you want to slide then browse to that folder so that the pictures get displayed in the Windows Desktop Background window. Once you have the pictures listed in the window select more than one image (you need more than one image to make a slide show). As soon as you will select more than one picture or wallpaper you will see that the dropdown titled “Change Picture Every”, and the check box “Shuffle” gets enabled. These two controls; the drop down and the check box control the sliding of the pictures. From the drop down you can select for how long each image should stay as wallpaper and from the check box you can control if the pictures should be applied in a sequence or at random. Once you are done with the picture selection, timeout selection, and random selection you can click on Save Changes button for the changes to apply and wallpaper slide show to begin.

Now you will see that the wallpaper will keep on changing and the images which you selected will keep on applying to the desktop. Though this is an eye catchy and quite interactive feature but should only be applied if you have ample amount of resources to waste on your computer. Everything which is visible or not visible on the computer acquires resources like memory and processor. Wallpapers are of quite a large size with many colors on it and get displayed as a bitmap image so it occupies a decent amount of RAM. Keeping single wallpaper requires memory and if we keep it changing at regular intervals then it will use more of the processing time and the RAM as well. So select this option if you have ample amount of resources otherwise you yourself will notice the system not responding momentarily while the image changes automatically.
