I'm looking for a way to restrict my users (800+ High School Students) from using picture folders to change their desktop background pictures, lots of random/inappropriate selfies popping up when I have to work on their machines. I know I can just set it to one photo at log in every time, but I will hear a bunch of crying about it if they cant pick a photo themselves..
This IS helpful, yet I'm just trying to restrict the use of folders and randomization of desktop picture slideshows. Making the process restricted itself will cause more complaints than the change is actually worth.
@TBenolkin Then restricting students from using the pictures folder to change their desktop background is going to have the same affect as my suggestions above.
The solution I have used in the past is to set the desktop background to change back to default on every login. If students want a custom background, they will change it.
This can be done quite easily with an ongoing policy!
