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 8.1 and Windows Server 2012 R2. The following are the most common:
Hard block
This prevents an application that is incompatible with Windows 8.1 or Windows Server 2012 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.
