The kinds of problems that are resolved by application compatibility updates

When you try to install and run certain games or applications in Windows RT, Windows 8, or Windows Server 2012, you may experience one or more of the following symptoms:

  • The game, the application, or the driver is installed incorrectly.

  • The game, the application, or the driver causes system instability.

  • The primary functions of the game, the application, or the firmware do not work correctly.

Applications or devices that experience a change in behavior after you install this update

The following table lists the applications and devices that are included in this cumulative update package. This table also describes the behavior of these applications and devices after you install the update.

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.

Soft block

This update puts a soft block on the application. The soft block notifies you when primary functionality of the application is broken, or when the application experience is unstable in Windows RT, Windows 8, or Windows Server 2012.

Driver block

This action may block an existing driver on your computer. When the driver is migrated during the upgrade, an Inbox driver is installed.
