Windows Server 2025 is the latest LTSC release from Microsoft. It brings new features for security, performance, hybrid management and licensing. In this article, you’ll find what’s new, a comparison with previous versions, and hosting advice for running Windows Server 2025 in the Netherlands.
Hybrid Cloud & Azure Integration
