Windows Admin Center (WAC) vMode (Virtualization Mode) is a current in-preview management gateway for Hyper-V environments, deployable as a stateful appliance with an integrated PostgreSQL database. Unlike aMode (Administration Mode), vMode targets centralized virtualization management across multiple hosts and clusters, without requiring System Center Virtual Machine Manager (SCVMM). The only mandatory prerequisite is the Microsoft Visual C++ Redistributable. This article covers the system requirements, environment preparation, and installer walkthrough for vMode, and briefly explains how aMode installation differs.
