The specific build you mentioned, Build 20348.587 , corresponds to the March 2022 update cycle . This release focuses on refining the core pillars of the operating system while addressing critical security vulnerabilities. Core Architecture and Security Foundations The hallmark of Windows Server 2022 is the Secured-core server designation. By partnering with hardware vendors, Microsoft ensures that the OS boots only with trusted code. Hardware Root-of-Trust: Utilizes TPM 2.0 (Trusted Platform Module) for secure key storage. Firmware Protection: Uses Dynamic Root of Trust for Measurement (DRTM) to prevent "bootkits." VBS and HVCI: Virtualization-based security isolates sensitive parts of the memory to block common malware injection techniques. Connectivity and Networking Enhancements Build 20348.587 benefits from significant upgrades to network protocols that improve both speed and privacy: HTTPS and TLS 1.3: Enabled by default, this protocol ensures faster handshakes and stronger encryption for web traffic. DNS-over-HTTPS (DoH): Encrypts DNS queries to prevent eavesdropping and traffic manipulation. SMB over QUIC: This "game-changer" for mobile users allows access to file shares over the internet without needing a VPN. SMB AES-256: Provides the highest level of encryption for data moving across internal networks. Hybrid Cloud Capabilities with Azure Microsoft designed this version to be "cloud-native" while remaining on-premises. Through Azure Arc , administrators can manage Windows Server 2022 instances across physical, virtual, and multi-cloud environments from a single dashboard. Azure Automanage: Automates best practices like patching and backup. Hotpatching: (Available in Azure Edition) Allows installing security updates without restarting the server, maximizing uptime. Platform for Applications and Containers Windows Server 2022 reduces the footprint of Windows Container images by up to 40%. This results in faster startup times and better performance for developers. Kubernetes Support: Enhanced networking for pods and better integration with Azure Kubernetes Service (AKS). Storage Migration Service: Simplifies the process of moving data from legacy servers to the 2022 environment. Understanding Build 20348.587 (March 2022) While the "Full" version includes the Desktop Experience (GUI), this specific build was a critical maintenance point. It addressed: CVE-2022-24508: Resolved a vulnerability in the SMBv3 protocol. Performance Fixes: Addressed memory leaks in the non-paged pool and improved UI responsiveness in the Desktop Experience. Stability: Corrected issues where certain virtual machines would fail to start after a series of updates. Get a step-by-step installation guide for the GUI (Full) version?
