This version of ACT supports Windows® 8. For more information about supported operating systems, see Software Requirements for ACT.

The runtime-analysis package gathers compatibility information. It is installed on computers for the purpose of compatibility testing for applications on the version of Windows that you want to deploy. The data from the runtime-analysis package replaces data from issue detectors that attempt to forecast compatibility issues by running on a previous version of Windows.

Data collection overhead has been reduced because the purpose of the inventory-collector package is now limited to inventory collection. The redesigned inventory-collector package does not cause application conflicts because it does not interact with applications. Scheduling the inventory-collector package to avoid conflicts is no longer required.

The application reports in Application Compatibility Manager (ACM) now show a single parent entry for an application where multiple versions of the application are detected. The multiple versions of the application are grouped together under this entry.

The ACT documentation has been streamlined to enable you to locate information quickly and conveniently.

ACT is now integrated into the Windows® Assessment and Deployment Kit (Windows ADK). You can install ACT by using ADK Setup.

Compatibility information is now focused on operating system deployment. Update compatibility has been removed.
