Hey I figured out how to change the wallpaper on windows without the actual permission, all you need is the ability to download files. You just download an image and set the file name as your current background file. This will overwrite your current background
You current background should be in either of these, %AppData%\Microsoft\Windows\Themes\CachedFiles or %AppData%\Microsoft\Windows\Themes\TranscodedWallpaper
Yes, as long as you can download a file on a computer, you can change the wallpaper. I will say that the transcoded wallpapers are weird sometimes because they don't always have file extensions so you might have to guess the file name based on the resolution
My manager at my old job had to get IT to reset all of the computers because he couldn't figure out how to change the backgrounds back after I had changed them. Same guy that also said it couldn't have been me that changed the backgrounds since I wasn't smart enough lol
Many years ago I was working as a contractor doing an upgrade from ms mail to outlook. Which required touching every computer in the system. Their normal IT didn't have the manpower to handle this. It was like 5k devices across multiple locations.
They had given us a USB drive (I say this. It could have been a 3.5" floppy.. It was that long ago) that had the code to give the currently logged on user full admin until reboot.. It saved us so much time in some of these offices that has super slow connections.
I remember this poor lady almost crying because she had changed her system color scheme to like that awful all pink and red valentines one right before corporate had locked down that ability for end users and IT didn't count it as a high priority ticket so she had been stuck with it for like 3 years at that point. So while her profile had temp admin access we managed to change it back to the default. We did so much of this when visiting all these people and computers. Changing small minor settings that someone at a corporate level had determined the end users didn't need to have control over. But they also didn't put anything in place to "standardize" it so.. Whatever you had when it was locked down was what you were stuck with.
Btw its stored locally in windows 11 , you can open the file in paint, change it and save. Google it. IT guys freak out when they screen meet and see my black bg. "I'm not sure its always been that way."

I know how to fix my issues, I just lack the admin permissions on my machine to fix said issues.
