Update information

How to obtain this update

This compatibility update is offered when you upgrade to the release version of Windows 8.1 or Windows Server 2012 R2.

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

    This puts an upgrade block on an application that may cause the upgrade to Windows 8.1 or to Windows Server 2012 R2 to fail. 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 providing 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 the user experience by warning the end-user and providing 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 or Windows Server 2012 R2 is installed.
  • Block upgrade, can reinstall

    This may block the upgrade to Windows 8.1 or Windows Server 2012 R2. To continue the upgrade, you must uninstall the application or driver. After Windows 8.1 or Windows Server 2012 R2 is installed, the application or driver can be reinstalled, and may then function correctly.
  • Reinstall after upgrade

    Allows the upgrade to the release version of Windows 8.1 or Windows Server 2012 R2 to complete successfully. However, you can reinstall the application or device after the upgrade.
  • Migration block

    This action blocks an incompatible application from being migrated either completely or partly during the upgrade from Windows 8 to Windows 8.1 so that the upgrade is completed successfully.
