Buying Windows Server keys

All Windows Server versions in one place. For a new server, go with Windows Server 2025 or 2022. Pick 2019 or 2016 when an application requires them, and 2012 R2 only for legacy systems, since its support ended October 10, 2023.
Editions

Standard: physical servers and up to two virtual machines per license.
Datacenter: unlimited virtual machines on the licensed host.
Essentials: small businesses, up to 25 users and 50 devices.

Some products include CALs. Separate Remote Desktop licenses are in Windows Server CALs. Activation runs with Microsoft, and the key comes with instant delivery to your email.
