I am wondering if it is possible to lock-down a Microsoft Surface RT tablet by allowing one application to always be in the foreground and restricting users from doing anything else.
Is it possible to lock down a Surface RT in this manner?
It looks like that Windows 8.1/Blue allows you to configure a kiosk mode/assigned access:
So, wait until MS release this later this year.
Check out a company called Faronics, they make good software for Kiosks. I don't know if they make Software for RT, but its worth a shot. Winselect is awesome for locking down windows systems.
