One problem that you might run into when trying to delete wallpapers in Windows 7, 8 or 10 is an error message saying that you first need permission from TrustedInstaller. Copy them back later on to have them show up in the list again. If you think you may actually want to use the wallpapers later, you can just cut them and paste them into a temp folder. Now you can simply delete all the images in this folder and they will be removed from the desktop background dialog the next time you open it. In Windows 7 and higher, you might find a couple of folders and those are the categories that I was mentioning above. In Windows XP, you’ll see some JPG and BMP images, the most famous being Bliss.bmp, which is the default desktop background for that operating system. In that folder you will see the default wallpapers installed on the system. The main place to look in every version of Windows is: In Windows 7, Windows 8 and Windows 10, the wallpapers are all stored in just one location. In Windows XP, there are a few locations where these annoying wallpapers are stored. Luckily, deleting the wallpapers is as easy as navigating to the correct folder and deleting everything there.

Windows 10 has another set of newly created wallpapers that will be shipping when it’s released this summer.
