This article introduces how to disable wallpaper in Windows 10.
To disable wallpaper in Windows 10, go to “Settings → Ease of Access → Other Options → Visual Options → Show Background” and turn it off. This setting is a configuration to not set wallpaper at all. It makes things slightly lighter, so it’s killing two birds with one stone.
Also, if you want to reset the wallpaper later, you might run into trouble with “Background is currently disabled by ease of access settings on your computer,” so it’s recommended to make a note of “Settings → Ease of Access → Other Options → Visual Options → Show Background.”
