Thoughts on Windows Server 2025

Hotpatch (updating without restarting) and the desktop experience of Windows 11 are new features. Support for NVMe over Fabrics (NVMe-oF) is also included.
Windows SMTP Server has been removed. Also, Active Directory appears to have undergone some significant modifications but I've noticed that many users are complaining about problems with Windows Domain Controller. Windows Server 2022 (EOSL) will only receive security upgrades after its mainstream support expires on October 13, 2026.
Is anyone using Windows Server 2025?

I have Windows 2025 in a VM on my homelab. I don't do much with it because I'm more of a Linux person myself despite having worked at Redmond itself for five or so years.
Office OS Server 2025. Bleeding-edge tech for Excel and Outlook. Like the other guy said, there's nothing to do much with it.
Windows Server 2025 don't even support RDP over UDP tho, and they haven't fixed it for half a year
wtf?
i am still with windows server 2022.
Just another way for them to make money. Not that many new features that can be easily implemented via windows updates
FYI, currently there are issues building Server 2025 and Windows 11 24H2 images with the virtio drivers if you want to use the OS on a KVM VPS.

You want new features for free, don't you?
I installed Windows Server 2025 on one of my servers a couple of days ago, and I am still exploring...
We are using Windows Server 2025 for some customers and it works fine so far. No complain
I find it slow when it searching for apps on a kimsufi server, where as on server 2022 it's instant
I have been playing with it and looking to deploy it where possible - I tend to have a policy of getting machines upgraded as quickly as is sensible. The AD upgrades are a very nice touch (database sizes being able to be increased to 32k pages, better default computer account password generation, TLS 1.3 for LDAP, etc).
IIS 6/SMTP support being totally removed is nice, it will force a few organisations with very very bad habits that are running legacy software to finally deal with them (in 2031 ofc when 2022 ESU go). Most of what is being deprecated or otherwise removed in my opinion is a good thing. MS hold on to the past too closely at times, a death day for Classic ASP needed to come sooner imo.
SMB over QUIC is a phenomenal change, and there are some nice upgrades to Hyper-V too.
If anyone wants the full list:

The only issue I've had /w rolling out 2025 is that the firewall rules seem to default to closed even if the box is a DC, because NLA thinks you're on a public network.

Hotpatch could corner the hobbyist hypervisor market if it wasn’t tied to Azure
