Upgrade actions

This compatibility update may trigger several actions when you upgrade to the latest version of Windows 8.1 or Windows Server 2012 R2. The following are the most common actions that may be triggered:

  • Upgrade block

Windows 8.1 and Windows Server 2012 R2 put an upgrade block on a third-party application only if the manufacturer is notified. The user must uninstall the application to continue with the upgrade.

  • Hard block

    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. Improves user experience by warning the end-user and provides a "more information" URL about the product.

  • Driver block

    May block an existing driver on your computer when you upgrade to Windows 8.1 or to Windows Server 2012 R2. If this occurs, a driver for Windows 8.1 and Windows Server 2012 R2 is installed.

  • Reinstall after upgrade
