Frequently Asked Questions

About Windows Server

Windows Server powers business-critical infrastructure — file sharing, Active Directory, virtualization, and application hosting — with the same enterprise-grade reliability and security Microsoft brings to millions of servers worldwide.

  • Genuine Microsoft server license keys
  • Supports Active Directory & virtualization
  • Core-based licensing for physical or virtual servers
  • Reliable, enterprise-grade security
  • Instant digital delivery after purchase
  • Ideal for business & IT infrastructure

Windows Server license keys activate Microsoft's server operating system, the foundation for running business applications, file and print services, virtualization, and Active Directory in a Windows environment. Every key is a genuine, one-time license.

Standard vs. Datacenter edition

Windows Server Standard is built for physical or minimally virtualized environments and includes rights to run up to two virtual machines per license. Datacenter edition is designed for highly virtualized datacenters and software-defined environments, with unlimited virtual machine rights on the licensed hardware.

Core-based licensing and CALs

Windows Server is licensed per physical core, with a minimum of 16 core licenses per server. Beyond the server license itself, each user or device accessing the server also needs a Client Access License (CAL), sold separately.

How delivery works

Your product key is delivered by email within minutes of payment, together with setup guidance for activating the server role.
