Windows Boot Manager not updated
KB5025885 outlines how to update Windows Boot Manager, but build 26257 still has a Windows Boot Manager that is signed with the old "PCA 2011" certificate. The manual processes in KB5025885 are a real pain (and don't scale) so it would be very annoying if this is not fixed before RTM. https://support.microsoft.com/en-us/topic/kb5025885-how-to-manage-the-windows-boot-manager-revocations-for-secure-boot-changes-associated-with-cve-2023-24932-41a975df-beb2-40c1-99a3-b3ff139f832dServer 2025 Core ADDS DC, Network Profile Showing as "Public" and not as "DomainAuthenticated"
OS: Windows Server 20225 Standard Core (no GUI), build 26085.1 Role: ADDS, DNS ForestMode: Windows2025Forest DomainMode: Windows2025Domain Platform: Hyper-V guest When standing up a clean Windows Server 2025 using server core and configuring it as a domain controller, the network category (profile) always shows as "public." A clean load of Windows Server 2022 with server core as a domain controller has the same behavior. However, in Server 2022, the fix is to add DNS as a required service to the nlasvc (Network Location Awareness) service. Once that is done, the network category reflects "DomainAuthenticed" and persists between reboots. In Server 2025, the nlasvc service does not have the same requiredservices as Windows Server 2022, and it does not start automatically. Even after configuring the nlasvc service the same way it is in Server 2022 and adding DNS as a required service, the network category still reflects "public." The only way to get the network category to properly reflect the "DomainAuthenticated" status is to disable and reenable the network adapter after each reboot.
Windows Server 2025 is generally available as of Nov 1!!

When will there be a preview build of Windows Server on ARM? There is demandfor it from developers, and devops personal as well. It is known that it already partial exists due to the article on Azure Host OS. Azure Host OS – Cloud Host - Microsoft Community Hub Please release this so we can test it against our code.
Snapdragon X Elite (Arm) Build of Windows Server 2025
Hello I can't seem to find where to download the evaluation build for Windows Server (ideally the more regularly updated Azure Edition) but all I seem to be able to find is x64. There seem to have been builds out there for months from screenshots but I'm not sure where people are getting them from. It seems build 26100.1742 would be the best one at least to start with before I switch to being overly canarified.b26085 - Windows Server 2025 Domain Controller fail to deploy via DSC
Hi there, I am trying to deploy mslab using Windows Server 2025 preview VM using Windows Server 2025 OS as a Hyper-V platform. I believe Jaromir as maintainer of mslab opened an SR. In result he updated the code, plus PS DSC Modules. edit: this issue is unrelated to the running SR. Still the deployment of the domain controller template will fail during first boot. This is not specific to b26085, this one is troubling for since WS2025 insider, so it never worked with this branch.

Initial configuration in progress. Sleeping 250 seconds Question: What could be reasons it keeps failing? We have no clue / pointers and imho it would be expected and necessary that mslab works with WS2025, despite being preview, too. Who at Microsoft could afford time to repro and looking into that? As mslab is also used by Microsoft, I hope anyone could spare time to investigate (with Jaromir and/or me). I personally can spare time for that investigation. Thank you very much in advance!
