Keep the desktop wallpaper centered

I often change the wallpaper, but every time I change it, it turns to tile, and every time I want to center it, it's really troublesome.

Solution:

HKEY_CURRENT_USER/software/Microsoft/Windows/CurrentVersion/policies/
Create an item named "system" under the registry key. (If the system item already exists under the IES branch, skip this step)

 
Create a "string value" named wallpaperstyle under System"

Wallpaperstyle has three definable values:
0 = center
1 = Tile
2 = stretch

 

When wallpaperstyle is set to one of the preceding three values (numbers), the "position" drop-down menu in the "desktop" tab of "Display Properties" is forced to show the corresponding value effect, and cannot be operated.
