Extending grace period.
I am currently evaluating Windows Server 2025 arm64 (from canary insider channel). However this evening the evaluation period finishes. Is it possible to extend for another 3 months? Thx, Fulco

AAD join Server 2025
Hi, Wondering if Server 2025 can be AAD joined. this would help some businesses that have their laptops joined as well as would also like to have the option to join their Server for their line of business apps etc. Seems really strange you can have win11 AAD joined but not server 2025. Or am i just missing something here. Having to use Azure Arc comes with extra headaches and costs.

Server 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.

In-place upgrade possibility planned for Windows Server 2025 Datacenter Azure Edition ?
There is currently no official ISO for Windows Server Datacenter: Azure Edition that supports setup.exe /auto upgrade for in-place upgrades. Azure Update Manager does not support OS version upgrades for Azure Edition through optional features. Is anyone aware of a supported workaround?

vNVMe on Hyper-V to unlock PCIe 5.0 NVMe performance
On hosts with NVMe PCIe 5.0 (E3.S/U.2), Hyper-V guests still use virtual SCSI and leave a lot of performance on the table. We are paying for top-tier storage, yet software becomes the limiter. A virtual NVMe device that preserves checkpoints/Replica/Live Migration would align guest performance with modern hardware without forcing DDA and its operational trade-offs.

With the removal of smtp from Windows Server starting with Windows Server 2025, microsoft should add postfix to the server in a similar manner to how ssh was added to windows server. The source code is actively maintained: https://github.com/vdukhovni/postfix.
