Windows Server 2025 now has an ARM64 build that’s available in preview.

I have it running in a VM on an Apple Silicon MacBook.

Performance is quite good even though it was only released a few weeks ago and isn’t officially supported by any of the VM apps.
 
Hey, just looking into this. Where did you get the ISO from? Do you have any basic instructions? I have seen it on UUP Dump, but not quite sure how to use that service yet. Any info kindly appreciated :) Thank you
 
You can try CrystalFetch, which is a free utility based off of UUPDump. It downloaded the files, but I received an error during the conversion step and it wasn't able to create an ISO.


The other way which worked for me is to use UUDump directly. The Mac and Linux versions of the download script don't include updates in the ISO.

Run the download package on Windows 11 on ARM using Parallels or VMware Fusion, or on a Windows PC.

1. Go to uupdump.net
2. Click on Downloads at the top
3. Click on a Windows Server arm64 build (the latest current release is 26212.5000 (ge_prerelease) arm64)
4. Choose a language
5. Choose the editions that you want
6. For download method, choose Download and convert to ISO
7. Tick Include updates (only if you will be running the download script on Windows)
8. Click on Create download package button
9. Extract the zip file that's downloaded to a folder
10. Locate the file named uup_download_windows.cmd and run it
The ISO creation process will take some time. When everything's done, you will see a "Press 0 to exit" message.
The ISO file can be found in the same folder where you extracted the ZIP archive

Thank you very much.

The issue I was having is that the downloads from uupdump were not bootable when I was adding them through VMware Fusion or UTM.

On Horizon, I installed Windows 11 and I am now trying your method. Let's see how that works.

I was trying to do all of this natively from OS X.

Thanks again for your input :)

Yes, I had to use a workaround to get it to boot a few weeks ago.

The latest version of the preview build is now bootable. I tried it with VMware Fusion and UTM.

I tried the latest one with fusion yesterday and did not work. I must be doing something wrong with the settings
 
When creating the VM in Fusion, are you selecting Windows 11 64-bit for the operating system?
 
I’m on Fusion 13.5.2
Me too.

Right good news.

I created the iso through windows 11.

I then used this iso on fusion, with the standard windows 11 settings and it's currently installing which is superb news.

Thank you very much.

I just wish I could run all my VM's on this over spec'd laptop, might need to buy one or two mini computers to run the rest of my testing/demo/playing about for my 64-bit stuff.

Thanks again :+)

I'm on 13.5.2 VMware Fusion I tried with UTM also the downloaded ISO image (Windows Server 2025 downloaded from UUPDump) seems to be loading first time and post which I goes for reboot and keeps loading again it's not moving to next mode for installation.

It's not properly picking the boot device to proceed (I'm unable to change UEFI to boot mode). Please advise

That's freakin' awesome! And about damn time! I cannot tell you how many Microsoft Ignite panels that I've been a part of wherein I and a bunch of others request this!

It'll be awesome when the others catch up. I'm still waiting for VMware Fusion to be supported by Microsoft for virtualizing Windows 11 for ARM64. I know Broadcom is trash, but I have never been much of a Parallels Desktop fan and, with VMware Fusion Pro being free now, it's the perfect time to get into this stuff!

I'm not sure what you're waiting for at this point, Fusion works fine for this, and you can download an installer for Win 11 inside of fusion 13.5.

It would be nice is VMware would hurry up and get the VM tools working so that we can share folders with the virtual machines.
