Update Compatibility Evaluator (UCE) Technical Reference
The Update Compatibility Evaluator (UCE) provides insight and guidance about the potential effects of a Windows operating system security update on your installed applications. The UCE dynamically gathers application dependencies, and is deployable to both your servers and client computers, in either a production or test environment. The compatibility evaluator collects information about the modules loaded, the files opened, and the registry entries accessed by the applications currently running on the computers, and writes that information to XML files uploaded to the ACT database.
You configure UCE from the Application Compatibility Manager, defining the deployment method and the evidence collection schedules. You can view your UCE reports from the Analyze screen of the Application Compatibility Manager.
