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

The following table lists the applications that were added to the cumulative update package. This table also describes the behavior of these applications after you install the update.

Application compatibility updates trigger several changes in Windows Vista SP2, in Windows Server 2008 SP2, in Windows 7, and in Windows Server 2008 R2. The following are the three most common:

  The update puts a hard block on the application. A hard block prevents an application that is incompatible with Windows 7 and with Windows Server 2008 from running on the system.
  
  Note Microsoft enables Windows to put a hard block on a non-Microsoft application only if the manufacturer of the application gives its consent.
• Soft block
  
  The update puts a soft block on the application. A soft block notifies you when an application that is incompatible with Windows 7 starts to run.
• Update
  
  The update improves the application’s functionality in Windows Vista SP2, in Windows Server 2008 SP2, in Windows 7, and in Windows Server 2008 R2.
