Datacenter edition. Heavy workloads. Virtualisation stack that's been stable on 2022 and you're not about to shake it up for the sake of a version number. You need to stay where your VMs are happy.
This Lenovo downgrade kit steps Windows Server Datacenter back from 2025 to 2022. Multilanguage support is in the box — well, in the key. ROK format means it's a digital license code delivered to you, no physical media to chase down.
You get the build your virtualisation layer expects, with a genuine Lenovo ISG key. One clean downgrade. No re-imaging the whole cluster for nothing
