Windows 8.1 has seen its third leak, arriving to file sharing websites as build 9374. Build 9374 of Windows 8.1 doesn't seem to include any huge changes, but there is one interesting new addition: Kiosk Mode.
Kiosk Mode can be found in the PC settings menu, and seems to be a way of locking down a device to a single Windows 8-style application. These apps can be selected to launch at login, with the app lockdown in place for user accounts. Kiosk Mode seems destined for business users, or someone who wants to set it up in an embedded-like terminal that runs a single application.
Retail units could be deployed to run a single application, or business devices that allow employees to run a line-of-business application.
