Hello,
Although this might be slightly outside my area of expertise, I've come across some useful information from Windows Server | Licensing Guide
Windows Server Essentials edition server is for small businesses with up to 25 users and 50 devices. A server license covers up to 10 cores and 1 VM on single-socket servers. Windows Server Essentials is available through our OEM Server Hardware partners only.
Windows Server Essentials edition permits use of one running instance of the server software in the physical OSE on the licensed server (in addition to one virtual OSE), if the physical OSE is used solely to host and manage the virtual OSE.
Windows Server Essentials will continue to cover a single server with up to two physical processors. It does not require Windows Server CALs, but is limited to 25 user accounts. However, Windows Server 2022 Essentials is only available through OEM licensing.
I hope this information helps.
Best regards,
Karlie
