Microsoft has released a new build of the Windows Server Long-Term Servicing Channel (LTSC) Preview. Today's build 25295 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 changelog to speak of, so it's unclear what's new in the bits that relate to Server, for a changelog of the build 25295 client, go here.

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:

  • [Server #####] Title of my feedback

What's New

There are no new features shared about this build.

Known Issues

While using Windows Recovery Environment (WinRE) or in doing a clean install of Build 25295, users may encounter rendering issues which create difficulty in using these processes. Build-to-build upgrade is unaffected.

Installing the Languages and Optional Features preview will put the Server in a state where SCONFIG does not reliable start up after login, and Remote Desktop functionality into the Server fails inconsistently. If you depend on either Remote Desktop or SCONFIG, you may wish to avoid installing the Languages and Optional Features preview.
