If we were using an MSI, then no discovery is needed as these are all common for Windows Installers. These are three of the key, foundational features of the new application model in 2012: installation, uninstallation, and detection. Because this is a per-user install, make sure that you perform this test using a non-admin account and temporarily disable UAC so that auto-elevation does not get in the way. Install the application on a test system to ensure that you know the correct command-line to silently install the application per-user, to discover and test the silent uninstallation string, and to gather information on how to detect if the application is actually installed. Note that enabling incremental updates on more than 300 collections is *not* recommended incremental updates is a resource intensive task that will tax your site system if not carefully controlled.

For this example, I created a new user and added them to the Bagginses collection within less than 10 minutes, this new user was automatically in my collection – no updating or intervention needed.

* Because Delta Discovery is enabled on both of my discovery methods and incremental updates is enabled on my collection, users newly added to the AD security group will automatically be added to the collection within about 15 minutes (5 minutes for delta discovery + 10 minutes for incremental updates).
