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

Application compatibility updates trigger several changes in Windows XP, in Windows Server 2003, in Windows Vista, in Windows Server 2008, in Windows 7, or in Windows Server 2008 R2. The following are the three most common changes:
  • Hard block

    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 R2 from running on the system.

    Note Microsoft enables Windows to put a hard block on a third-party 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 and with Windows Server 2008 R2 starts to run.
  • Update

    The update improves the application’s functionality in Windows XP, in Windows Server 2003, in Windows Vista, in Windows Server 2008, in Windows 7, or in Windows Server 2008 R2.
The following tables list the applications that were added to the cumulative update package. These tables also describe the behavior of these applications after you install the update.
