When you set the background image of your desktop, Windows saves a thumbnail image of that image in the background. Here are the last five images that were used as background, even if you accidentally clicked on the wrong image while browsing. With a few simple registry edits you can remove one or all and start with a clean state.
Delete recent background images by editing the registry manually
If you accidentally add a picture as wallpaper If you want to get rid of it, you can not just right-click on it and delete it. Sure, you could add five more pictures, but using this registry editing is much easier to do.
Default Alert : The Registry Editor is a powerful tool whose abuse can make your system unstable or even inoperative. This is a pretty easy hack, and as long as you follow the instructions, you should not have any problems. If you've never worked with it before, you should think about how to use Registry Editor before you start. Back up the registry (and your computer!) Before making any changes.
Open the Registry Editor by pressing Start and typing regedit. Press Enter to open Registry Editor and allow changes to your PC
In the Registry Editor, use the left sidebar to navigate (or copy and paste) the following key Paste it into the address bar of Registry Editor):
HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion Explorer Wallpaper
After opening the key
Wallpapers you will see a number of values on the right side. The only ones we're interested in have names starting with
BackgroundHistoryPath followed by the numbers 0-4. These values indicate where to find the last five images used for your background.
Now you can, depending on which images you want to delete, delete one or all of them here by right-clicking a value-0 is the first image and 4 is the fifth and then select "Delete" the context menu. You can also delete multiple images at once, as in our example. After you delete it, Windows prompts you to confirm that you want to make changes to your registry.
If you delete something from the history, Windows automatically rebuilds these values and populates them with the default wallpaper
When you're done, you can close the Registry Editor. You must close the Settings app if it was open to update the history. If that does not work, you'll need to log out and log back in to Windows (or restart Windows Explorer) for the changes to take effect.
