Windows Server vNext build 25346 released to Windows Insiders

Microsoft has released a new build of the Windows Server Long-Term Servicing Channel (LTSC) Preview. Today’s build 25346 is now available to download as an ISO from the Windows Server Insider website along with a VHDX. It contains both the (Windows 11) Desktop Experience as well as a Server Core installation option for Datacenter and the Standard edition.

As per usual, there’s no full changelog between builds to speak of but there is a dedicated blog post. The Windows Server Preview now aligns with the Windows Insider Canary channel, which might indicate we won’t see a new Server version until next year when Windows 12 is expected to be released.

Branding has not yet been updated and remains as Windows Server 2022 in the preview. In addition, Microsoft is encouraging Insiders to give feedback in the Windows Server category and then the appropriate subcategory. The company asks to indicate the build number you are providing feedback on along with the title as shown in the example below:
