Windows Server 2022 is the cloud-ready operating system. It delivers new layers of security and Azure-inspired innovation for the applications and infrastructure that power your business.
Windows Server 2022 helps accelerate time to value by simplifying your underlying infrastructure. Moreover, it allows you to reduce cost by taking advantage of industry-standard hardware.
At the heart of the Microsoft Cloud Platform, Server brings Microsoft’s experience delivering global-scale cloud services into your infrastructure.
Windows Server 2022 introduces advanced multi-layer security, hybrid capabilities with Azure, and a flexible application platform. As part of this release, we are bringing secured-core capabilities to help protect hardware, firmware, and Windows Server OS capabilities against advanced security threats.
Secured-core server builds on technologies such as Windows Defender System Guard and Virtualization-based Security to minimize risk from firmware vulnerabilities and advanced malware. The new release also provides secured connectivity that introduces several new capabilities such as faster and more secure encrypted HTTPS connections, industry standard SMB AES 256 encryption and more.
Windows Server 2022 improves hybrid server management with significantly improved VM management, an enhanced event viewer, and many more new capabilities in Windows Admin Center. Furthermore, this release includes significant improvements to Windows containers, such as smaller image sizes for faster download, simplified network policy implementation and containerization tools for .NET applications.
Windows Server 2022 builds on Windows Server 2019, our fastest adopted Windows Server ever. This release includes advanced multi-layer security, hybrid capabilities with Azure, and a flexible platform to modernize applications with containers.
Windows Server 2022 Features:
Advanced multi-layer security
With a growing number of cyber-security threats and the impact of incidents escalating quickly, security is a top priority for our customers. Windows Server 2022 includes new security capabilities like secured-core server and secure connectivity.
Secured-core server brings powerful threat protection together to provide multi-layer security across hardware, firmware, and the operating system. It uses the Trusted Platform Module 2.0 and System Guard to boot up Windows Server securely and minimize risk from firmware vulnerabilities. Secured-core server also includes virtualization-based security (VBS) features like Credential Guard and Hypervisor-protected code integrity (HVCI). Credential Guard provides preventative defense for sensitive assets like credentials, and HVCI applies hardware – rooted security to prevent advanced malware from tampering with the system.
Secured connectivity adds an additional layer of security during transport for advanced protection. Windows Server 2022 improves connection security with faster and more secure encrypted hypertext transfer protocol secure (HTTPS) and transport layer security (TLS) 1.3 enabled by default. Customers can also further secure server communications with industry-standard AES-256 encryption, which now supports server message block (SMB) protocol and better controls.
Hybrid capabilities with Microsoft Azure
The new capabilities enables customers to take advantage of cloud innovation with their on-premises investments. Azure Arc and Storage Migration Service are two key hybrid capabilities that work best with Windows Server 2022.
Azure Arc enables customers to manage, secure, and govern Windows Server on-premises, at the edge, or in multi-cloud environments from a single control plane in Azure. Through Azure Arc, customers can easily employ Azure management capabilities such as Azure Policy, Azure Monitor, and Azure Defender for those servers. What’s more, a few simple clicks in Windows Admin Center can enable connectivity to Azure Arc. Further, has been enhanced Windows Admin Center v2103 with significantly improved virtual machine management, a simpler event viewer, and many more updates. Windows Admin Center is also available in the Azure portal.
Windows Server 2022 enhances the seamless connectivity of file servers on-premises to file servers on Azure. Updates to Storage Migration Service allow customers to migrate file servers from NetApp FAS to Windows Servers. Using Storage Migration Service to migrate data to servers allows customers to maintain low latency while reducing their on-premises storage footprint.
Flexible application platform
Customers use Windows Server to run large-scale and distributed applications. Consequently, we have placed relentless focus on bringing platform capabilities and tools that improve developer velocity and support for business-critical workloads like SQL Server.
In this release, we are adding several platform improvements for Windows Containers, including application compatibility and the Windows Container experience with Kubernetes. A major improvement includes reducing the Windows Container image size, which leads to faster download time and better performance. In addition, you can now run applications that depend on Azure Active Directory with group Managed Services Accounts (gMSA) without domain joining the container host. Furthermore, there are several other enhancements that simplify the Windows Container experience with Kubernetes. These enhancements include support for host-process containers for node configuration, IPv6, and consistent network policy implementation with Calico.
In addition to platform improvements, updated Windows Admin Center tool makes it easy to containerize .NET applications. Once the application is in a container, you can host it on Azure Container Registry to then deploy it to other Azure services, including Azure Kubernetes Service.
Windows Server 2022 supports business-critical and large-scale applications like SQL Server that require 48 TB of memory and 2,048 logical cores running on 64 physical sockets.
- Fixed an issue resulting in the background of some dialogs to unexpectedly appear grey instead of white in the last couple flights.
- Fixed an issue resulting in the taskbar occluding the Power button in the Start menu for some Insiders recently.
- Fixed an issue resulting in some Insiders seeing a SYSTEM THREAD EXCEPTION NOT HANDLED bug check.
- Fixed a crash with opengl32.dll.
- Ffixed an issue that could result in the Settings app hanging when checking for updates right after upgrade.
- Fixed an issue that could result in the Settings app sending a notification that just said “new notification”.
- Ffixed an issue resulting in the Search Indexer not being able to retrieve metadata from HEIF and WebP files, so you couldn’t search for those files using metadata like date taken.
- Ffixed an issue resulting in the Cast to Device option in Movies & TV (and other media playback apps) not taking any action when clicking on a listed device in recent builds.
- Fixed an issue in recent builds that could result in the screen you were projecting with Miracast freezing shortly after connecting.
Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the processor cache. The following are the processor requirements for this product:
- 1.4 GHz 64-bit processor
- Compatible with x64 instruction set
- Supports NX and DEP
- Supports CMPXCHG16b, LAHF/SAHF, and PrefetchW

Choose an edition and an installation option:
Customers who download the full ISO will need to choose an edition and an installation option. This ISO evaluation is for the Datacenter and Standard editions. The Datacenter edition is the most complete edition and includes the new Datacenter-specific features (Shielded Virtual Machines, Storage Spaces Direct, and Software-Defined Networking) in addition to unlimited server virtualization.
- Server Core: This is the recommended installation option. It’s a smaller installation that includes the core components of Windows Server and supports all server roles but does not include a local graphical user interface (GUI). It is used for “headless” deployments which are managed remotely through Windows Admin Center, PowerShell, or other server management tools.
- Server with Desktop Experience: This is the complete installation and includes a full GUI for customers who prefer this option.
When you complete your evaluation, you can convert your evaluation versions to retail.
