Announcing Windows Server Preview Build 25951

Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions. Branding has not yet been updated and remains as Windows Server 2022 in this preview - when reporting issues please refer to "VNext" rather than Windows Server 2022 which is currently in market.

Known Issues

Upgrades from existing Windows Server installations are not supported with Annual Channel for Containers previews. You must perform a clean install.

This build has an issue where archiving eventlogs with "wevetutil al" command causes the Windows Event Log service to crash, and the archive operation to fail. The service must be restarted by executing "Start-Service EventLog" from an administrative command line prompt.
