App pinning is available on Android and it allows us to Pin an open running App to the screen so when someone else wants to use our computer, we only let them to use one open application/software/program, not others. if we pin an open App or software to the screen, the other person who is using our computer will only be able to interact with that 1 application/software. they won't be able to interact with other programs or even the OS. if they want to exit this pinned screen mode, they would have to enter the Windows PIN code.
this is really helpful. sometimes I want to let someone else use a program on my computer and don't want them to interact with other programs, file manager or Windows settings, so with this feature, I can restrict their interaction only to that one program or app.
