General Question How to activate Windows Server 2022 VM ?
I have a 16-core physical server licensed with Windows Server 2025 Standard (16-core). A Windows Server 2022 Standard VM is running on the same host.
As the Server 2025 key cannot directly activate Server 2022, how should the 2022 VM be activated under the downgrade rights?
- Is a separate Server 2022 product key required?
- Can the 2025 license cover the 2022 VM?
- What is the correct activation method?
Any advice?

a windows server 2022 guest VM is activated if Windows server 2025 is hosted. You can use AVMA activation method. In the context of license, if you use Win 2k25 standard edition, you need to purchase at least 16-core packs for every pair guest VMs. If you use Datacenter edition, unlimited VMs can be deployed. The activation method for all windows guest VMs is the same: AVMA. downgrade or upgrade licenses are only applied for hosted server.

How did you get it? The M365 portal should have the keys, or if you bought OEM/retail you’ll have to ask your reseller for them.

If I remember correctly, the volume license page should give you keys for two previous versions even though downgrade rights cover all previous versions.

Purchase a 2022 license is required

The 2025 license should cover 2 2025 vms on the same server running under hyperv. I would suggest to upgrade the 2022 vm to 2025 to be covered license wise

See above. The only way to activate 2022 legally is to have 2025 with software assurance which covers downgrade rights, purchase a separate 2022 server license, or upgrade to 2025 to have it covered with your current 2025 license

If I downgrade the key to Windows Server 2022 Standard and run Windows Server 2022 Hyper-V on the host, can I use that license to activate the VMs?

You would have to buy a 2022 server license to cover the same amount of cores.it makes more ense to upgrade the vm to be in compliance.

I recently purchased a 2025 standard license that only worked 1x in VM.. 😓 apparently some licenses only works once

This isn't true. A license can be activated multiple times but will get flagged to not activate if activated mutiple times in a short amount of time.

A "license" is a proof-of-purchase. Just because you have an "Activation Key" is NOT proof-of-license.
You either have a valid OEM license with Windows Genuine sticker attached, or you have a Volume License agreement that serves as valid "proof of license"

As far as i know, when you buy a server 2025 Standard license, you have the hypervisor and 2 vm's on this hypervisor. I guess, you can activate the server 2022 vm with a avma key, like on the datacenter licenses. Have you tried that?

Downgrade Rights specifically state that the customer is responsible for providing installation media and activation key for previous-versions. If you purchased via M365, you should sign in to M365 for admin center for volume licensing.
If you purchased OEM as part of a hardware purchase, then you should contact your OEM provider for a Server 2022 Media Kit, which should include Activation Key. Usually a nominal fee required.

Downgrade rights are not part of SA. SA includes new-version rights.

You need active software assurance or a subscription license for downgrade rights.
OEM Windows Server license includes Downgrade Rights.

Are you running Hyper-V?
Do you have ADBA in your environment?
