Application Compatibility actions apply the dynamic application of Microsoft Application Compatibility shims to a target application.
The Application Compatibility folder contains the following actions:
Application Compatibility Testing
Enable UAC Virtualization - turns of UAC virtualization for this target process.
Java - Win 2000
Virtualize Registry for Arellia Malicious Demo Application Compatibility
After analyzing Application Compatibility Testing logs and creating an elevation policy using the Adjust Application Compatibility wizard, which creates both the policy and the action, a new Application Compatibility action is created in the Application Compatibility folder.
Note
If you have legacy software running on Windows 7, then you will use the Application Compatibility action to allow that software to work without manual compatibility adjustments.
