Looking for software for a library that when it logs out, the profile goes back to default

[Henktank]

I need some help please, looking for some type of software for a library where people can use the computer free, but after a certain time of idle it logs outs and bring the users profile back to before they logged in. I've been searching but can't find this and I know they exist. If you know of any software like this please reply, thanks

Not familiar with how it works/what goes into setting it up, but my school uses deep freeze.
