Windows Server 2019 is mature, well documented and supported until January 2029. It brought Windows Admin Center, Storage Migration Service, System Insights and Kubernetes support, and runs most line-of-business applications. If you need support past 2029, choose Windows Server 2022 or Windows Server 2025.
Windows Server Standard and Datacenter require a Client Access Licence (CAL) for each user or device that connects to the server. Remote Desktop Services needs separate RDS CALs on top of that, beyond the two administrative sessions included with every server. Choose RDS User CALs when people connect from several devices, or RDS Device CALs for shared PCs. Our RDS CAL activation guide explains installation.
Install the matching edition, then enter your key under Settings → Activation or run slmgr /ipk YOUR-KEY followed by slmgr /ato as administrator. To convert an evaluation install, use DISM /online /Set-Edition with your key.
Essentials is limited to 25 users and 50 devices on one processor but needs no CALs. Standard scales further and includes two VMs, with CALs required.
Two per fully licensed server. Datacenter allows unlimited VMs.
Security updates continue until January 9, 2029.
Yes, with DISM and a Datacenter key, without reinstalling.
Yes, for more than two simultaneous admin sessions. Choose user or device CALs to match how people connect.
