App-V, or Microsoft Application Virtualization, lets companies run apps in a virtual environment and then serve those virtual apps to client computers. Windows 10 Enterprise includes a few virtualization features designed for companies that that have many computers connected to a server. If this sounds interesting, we've shown how to lock down Windows user accounts using other methods. Anything that isn't explicitly allowed through AppLocker won't run on the computer, making it a great tool for environments that deal with highly sensitive information. It allows you to create a whitelist of apps that are allowed to run on the system. AppLocker is a security feature that's not available in Windows 10 Pro.
