Shell restricting access, what?

Question

System administration

Hello, dear toasters, there was a need to restrict access to all windows except for one software, of course, for a while, so that you could then enter the password and a normal explorer would open.
It's quite difficult to make such a google request, and thoughts come to mind about the shells that are used in computer clubs, but there are strangely few pirates, and everyone requires a server. Please help, does anyone have any other options?

Answer 1

And if the user immediately instead of the limiting shell, put this softina?
The user logs in - and there, instead of working software, software is immediately available. Gets out of it - immediately logs out.
If the software is not designed to work in a secure environment, an advanced user can and will be able to launch a process from it. But for regular office users, this may be enough.
We disable the launch of the task manager, we prescribe your software instead of the explorer for the desired user and that's it.
