Applications or devices that experience a change in behavior after you install this updateThe 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 7 and in Windows Server 2008 R2. The following are the most common:
The update puts a hard block on the application. A hard block prevents an application that is incompatible with Windows 7 or Windows Server 2008 R2 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.
This update puts a soft block on the application. A soft block notifies you when primary functionality of the application is broken on Windows 7 or Windows Server 2008 R2, or causes instability of the application experience.
This action may block an existing driver on your computer. When the driver is migrated during the upgrade, an Inbox driver will be installed.
