Windows Server 2022 LTSC released
Microsoft released a new version of Windows Server this week, Windows Server 2022 LTSC. The new version of Server doesn’t really need the LTSC descriptor anymore, as Microsoft announced earlier this year that all future versions of Windows Server will be long-term service channel releases.
Windows Server 2022 LTSC will be supported for ten years. Five of those years with general support and the remaining five years with extended support. The main difference between the support phases is that the extended support is limited to security updates and bug fixes. Standard support may also introduce new features in the Server version.
Consumer support ends October 13, 2026, extended support ends October 14, 2031.
The “What’s New in Windows Server 2022” support page lists major changes in the new version of the server.
Here is a brief overview:
- Security enhancements: secure central server, simplified security, hardware root of trust, firmware protection, virtualization-based security (VBS)
- HTTPS and TLS 1.3 enabled by default.
- Secure DNS support with DNS-over-HTTPS.
- Server message block AES-256 encryption.
- SMB East-West encryption of the server message block.
- PME on QUIC.
- Azure Arc enabled.
- Azure Automanage – Hotpatch.
- Platform improvements, such as application compatibility and the Windows Container experience with Kubernetes.
- Nested virtualization for AMD processors.
- New Microsoft Edge web browser.
- Storage migration service.
- Adjustable storage repair speed.
- Storage bus cache with storage spaces on stand-alone servers.
- SME compression.
Windows Server 2022 is available in three editions: Windows Server 2022 Standard, Windows Server 2022 Datacenter, and Windows Server 2022 Datacenter: Azure Edition.
There are quite a few differences in terms of functionality between the versions. Hotpatching is only supported by Azure Edition, Storage Spaces Direct only by Datacenter Editions, and Standard Edition is limited when it comes to Storage Replica.

This The Microsoft Docs web page lists features that are no longer in development or removed:
|Internet Storage Name Service (iSNS) server service||The iSNS Server service has now been removed from Windows Server 2022 after being considered for removal in Windows Server, version 1709. You can still connect to iSNS servers or add iSCSI targets individually.|
No longer in development:
|Protected structure and protected virtual machines (VM)||Windows Server and Azure Stack HCI align with Azure to take advantage of continuous improvements to Azure Confidential Computing and Azure Security Center. This alignment translates into the extension of more cloud security offerings to customer (on-premises) data centers.
Microsoft will continue to provide support for these features, but there will be no further development. On client versions of Windows, the Remote Server Administration Tools (RSAT): Protected Virtual Machine Tools feature will be removed.
|Launch SConfig from a Command Prompt window (CMD) by running
||Starting with Windows Server 2022, SConfig is launched by default when you log in to a server running the Server Core installation option. Additionally, PowerShell is now the default shell on Server Core. Exiting SConfig takes you to a standard interactive PowerShell window. Likewise, you can unsubscribe from the automatic launch of SConfig. In this case, you will get a PowerShell window upon login. In either case, you can launch SConfig from within PowerShell by simply running
