Compatibility updates trigger several changes in Windows RT, Windows 8, and Windows Server 2012. The following are the most common. 

Hard block

The update puts a hard block on the application. The hard block prevents an application that is incompatible with Windows RT, Windows 8, or Windows Server 2012 from running on the system.

Note Microsoft enables Windows to put a hard block on a non-Microsoft application only if the manufacturer is notified.
