Microsoft is set to release Windows Server 2025 in November 2024, featuring several editions: Essentials, Standard, Datacenter, and Datacenter Azure. Windows Server Essentials is limited to servers with a single CPU and fewer than 10 cores and can only be obtained through hardware OEMs. The Standard edition allows Hyper-V licensing for up to two virtual machines, while the Datacenter edition has no such limits and offers more flexibility with disaster recovery features. The Datacenter Azure edition is optimized for the cloud and receives annual updates.
The hardware requirements for Windows Server 2025 include a minimum 64-bit CPU at 1.4 GHz, support for various instructions, and the ability to accommodate up to 2,048 logical processors. The minimum memory requirement is 512 MB, with 2 GB recommended for optimal performance. Storage requirements suggest at least 64 GB for better performance, especially with Desktop Experience, and a Gigabit Ethernet adapter is necessary for networking.
Several features have been deprecated in Windows Server 2025, including Computer Browser, Failover Clustering Cluster Sets, and NTLM, among others. Completely removed features include IIS 6 Management Console, NTLMv1, and Windows PowerShell 2.0 Engine.
Organizations planning to migrate to Windows Server 2025 must ensure their hardware meets the minimum requirements and can perform an in-place upgrade if currently using Windows Server 2012 R2 or newer. Testing in a lab environment and backing up servers before migration are recommended steps.
