Windows Server Summit 2026 Day 2 continues to celebrate that Windows Server 2025 is now over a year old. After Day 1 and it’s focus on roadmapping, Windows Server 2025 Hyper-V and the future operational stack, we now look into Azure Arc, Azure Virtual Desktop, Active Directory and PKI. Let’s look into Day 2 together.

Introduction to Windows Server Summit 2026 Day 2

The Windows Server Summit 2026 Day 2 focused heavily on practical modernization, hybrid management via Azure Arc, and the groundbreaking integration of local AI workloads directly within your own data center. Following the strategic insights and core improvements highlighted on Day 1, the product focus on Day 2 demonstrated how established infrastructures can be efficiently transformed into a modern control plane.

For adaptive cloud architects, it is becoming increasingly clear that the boundary between on-premises infrastructure and cloud-native services is completely disappearing. Managing thousands of virtual machines, automating security policies, and utilizing AI inferences no longer require complex third-party tools but are natively embedded into the operating system.

From planning to push-button: Windows Server feature updates

This session lead Rob Hindman showed how in-place upgrades are becoming a reliable standard process in modern infrastructures. I couldn’t agree more and we have succesfully upgraded hundreds of server by now. If you are interested in how and what are our challenges, please get in touch with me.

• 4:15 to 6:02 Demonstration of media-based upgrades while skipping up to four operating system generations.

AI workloads on Windows Server

Jeff Woolsey presented the technical foundations that make Windows Server 2025 a premier on-premises platform for artificial intelligence. This session combines a lot of Hyper-V new features and combines them with Winget, SQL Server 2025, the new NVMe performance option to deploy i.e. Ollama.

Personally I think this is a not so strong session. It is an approach to show how to do AI on Windows Server 2025, but it’s nothing new or Windows Server 2025 specific.

If you are interested in Local Foundry you can watch 6:00 to 8:39. This was my biggest take away about AI on Windows Server 2025 and something new for me.
