Windows Server 2019 vs 2022: Key Differences Explained

Choosing between Windows Server 2019 and Windows Server 2022 comes down to a few core questions: how much you value the latest security hardening, whether hybrid cloud matters to your business, and which roles or features your workloads still depend on. In this guide we walk through the most important changes so you can decide which release fits your infrastructure.

Windows Server 2022 has been on general release for some time now and is offered in two main editions:

• Windows Server 2022 Standard (2–30 cores)
• Windows Server 2022 Datacenter (2–48 cores)

If you are already running Windows Server 2019 or 2016, the decision to upgrade will usually rest on the improvements Microsoft has introduced around security, cloud integration and manageability. For a broader overview of the platform, our guide to everything you need to know about Windows Server 2022 is a good companion read.

Security: a major step forward in 2022

The biggest single reason organisations move from Windows Server 2019 to 2022 is security. Windows Server 2019 introduced Microsoft Advanced Threat Protection (ATP), which uses machine learning to detect malicious files and suspicious behaviour on the server. Windows Server 2022 keeps those capabilities and layers on a new "secured-core" approach built around three pillars:

• Hardware root-of-trust
• Virtualisation-based security (VBS)
• Firmware protection

Together, these help protect the server from threats that target firmware and the boot process, which traditional antivirus tools cannot see. Secure connections are also strengthened: HTTPS and TLS 1.3 are enabled by default, and SMB now supports AES-256 encryption.

Hybrid cloud and data management

With cloud adoption now the default for most businesses, management and storage that stretch across on-premises and Azure matter more than ever. Windows Server 2019 introduced Features on Demand (FOD) and early hybrid capabilities. Windows Server 2022 goes further and makes the move to the cloud noticeably smoother.

If your organisation has not yet migrated parts of its workload to the cloud, Windows Server 2022 can help simplify that journey. The benefits typically show up in central management, data storage, faster access to resources across sites, and more flexible capacity planning.

Windows Server 2022 also ships with tighter integration with Azure Arc, so you can inventory, govern and update servers (including virtual machines) from the Azure portal, regardless of where they physically run. Storage Migration Service has been improved as well, making it easier to move file servers and their data onto newer hardware or into VMs.

Features that are no longer in Windows Server 2022

Every major release also retires older components. Some features that were available in Windows Server 2019 have been deprecated or removed in 2022, including:

• Shielded virtual machines
• Internet Storage Name Service (iSNS)
• Certain elements of the legacy SConfig experience

For most environments, these removals are not a blocker: Microsoft has replaced them with more modern alternatives, such as the refreshed SConfig tool and improved security tooling for virtual machines. Still, it is worth checking your current server roles against Microsoft's deprecation list before planning an upgrade.

Which version should you choose?

The short answer: if you are deploying new hardware or planning a refresh, Windows Server 2022 is the sensible choice. You get the strongest security posture, the best hybrid cloud integration and the longest support runway. Windows Server 2019 still makes sense when you need to match an existing estate, support an application that has not yet been certified on 2022, or keep costs down on a server that will run a limited, well-understood workload.

If your wider stack also includes SQL Server, it is worth reading our overview of Microsoft SQL Server 2019 to make sure your database tier is aligned with the operating system you choose.

Summary

The main differences between Windows Server 2019 and Windows Server 2022 come down to security hardening, hybrid cloud integration and a handful of deprecated legacy features. For most businesses planning an upgrade in 2026, Windows Server 2022 is the stronger long-term bet.
