The kinds of problems that are resolved by application compatibility updates

When you try to install and run certain games or applications in Windows 8 or in 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, of the application, or of 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 were 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 8. The following are the three most common:

Hard block

The update puts a hard block on the application. A hard block prevents an application that is incompatible with Windows 8 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. A soft block notifies you when one of the primary functionality of the application is broken on Windows 8 or causes instability to application experience.

Driver Block

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