When a hard block is put on an incompatible application, you cannot run the application after you upgrade. Windows 8.1 and Windows Server 2012 R2 put a hard block on a third-party application only if the manufacturer is notified. Improves the user experience by warning the end-user, and provides a "more information" URL about the product.
  • Soft block

A soft block notifies you when a primary function of an application may not work or may cause application instability.
