Microsoft is retiring the legacy WebRTC-based optimization for Teams in Virtual Desktop Infrastructure (VDI) and replacing it with a new architecture called SlimCore — also referred to as VDI 2.0 — introduced in Q4 2024. The change affects Windows endpoints connecting to Azure Virtual Desktop (AVD), Windows 365, and Citrix, with defined End of Support and End of Availability milestones. In parallel, Microsoft has announced a public tech preview of the new optimization for Omnissa Horizon. This article covers the architectural differences, supported platforms, new features, and the steps required to complete the migration.

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.

Organizations running modern data centers increasingly need flexible storage architectures that balance performance, resiliency, and investment protection. With Windows Server 2022 and Windows Server 2025, Microsoft now enables true S2D and SAN coexistence—allowing Storage Spaces Direct (S2D) to operate alongside traditional SAN storage within the same failover clustering environment. This mixed-storage approach lets IT teams optimize workloads such as Hyper-V, SQL Server, and file services by combining high-performance local storage with existing enterprise SAN infrastructure, all while maintaining full cluster support and operational consistency.

Microsoft announced a new virtualization mode in Windows Admin Center, specifically designed for managing Hyper-V infrastructure. This mode allows centralized control of hosts, clusters, storage, and networking. Positioned as Microsoft's alternative to VMware vCenter Server, this new mode complements the existing administration mode by focusing specifically on large-scale virtualization environments.
