Microsoft has released a new build of the Windows Server Insider Preview. This month"s build 25246 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.
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:
