Wallpaper change in windows 10

You can set the wallpaper using the Local Group Policy Editor (gpedit.msc), at User Configuration > Administrative Templates > Desktop > Desktop, group policy "Desktop Wallpaper". Set the policy to Enabled, enter the file path and click OK.

In the registry, this is set at key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System (you may need to create missing sub-keys). Create two REG_SZ items, one named Wallpaper for the path to the image file, and the other WallpaperStyle whose value is 4.
