Getting tired of seeing the same old image over and over when you turn on the PC? That should not be a problem, as you can change that image or remove it whenever you heart desires. Simply right click on the desktop and select a different picture to use as your background. However, after you have done this multiple times and accumulated a wealth of images, you will find a good deal of space has been occupied by desktop pictures you no longer wish to have. And here comes the tricky part: sometimes you can’t even change the desktop wallpaper no matter how hard you try.
Before moving on the more complicated issue of why you can’t switch to a new wallpaper, you should know that eliminating those unwanted images is extremely easy. Just go to the folder where you keep them and delete anything that comes your way. If you want to delete (or add to) the system’s default background images, know that they are all kept in a folder under My Documents.
Of course, there is the case in which you may not want any background image to be shown. Right click on the desktop, make your way to the background tab and select “none” in the menu where you would usually select an image. But the chances are that, if you had any previous experience with PCs, you already know all this.
Some issues appear when you try to use Active Desktop. This is a neat feature that allows you to add different interactive options to an otherwise normal wallpaper. With it, you can even set a web page to act as your wallpaper.
But for all its might and glory, it can also cause some problems when it comes to using another image for the background. Most often, this issue should go away if Active Desktop is turned off. You can do that by going to Control Panel, and selecting the Desktop tab. Once there, you will find a button that allows you to customize the desktop. Under the latter option, a Web tab will appear; uncheck every box there and then save and exit. This will do the trick in deactivating any interactive features, so you should be able to change or remove wallpaper at will.
Sometimes, however, the problem goes even deeper: adware and spyware can be the culprits behind it. You know if this is true when you try to change or remove the wallpaper and the tab or some options that are not available (grayed out). To solve this, you must delete some registries.
Press the “Start” button then select “run”, afterwards type REGEDIT in the dialog box. You will notice some plus (+) signs next to some sections. Click it for HKEY_CURRENT_USER then make you way to the Software section, after which select Windows. Go through Current Version, then Policies, and finally System. This is where you must look for a WALLPAPER key, and delete it. In almost every case this should solve all problems you might have with removing a desktop wallpaper or replacing it with another.
