Windows RT Question:

While Windows RT devices can join a Homegroup, files cannot be shared directly from the device itself. However, users can still access network shares on other devices within their Homegroup. Windows RT does not support connecting to a domain for network logins, nor does it support using Group Policy for device management. However, Exchange ActiveSync, the Windows Intune service, or System Center Configuration Manager 2012 SP1 can be used to provide some control over Windows RT devices in enterprise environments, such as the ability to apply security policies and provide a portal which can be used to sideload apps from outside Windows Store.
