Windows Server (formerly Windows NT Server) is a group of server operating systems (OS) that has been developed by Microsoft since 1993. The first OS that was released for this platform is Windows NT 3.1 Advanced Server, an edition of Windows NT 3.1. With the release of Windows Server 2003, Microsoft started releasing new versions under the name Windows Server. The latest release of Windows Server is Windows Server 2022, which was released in 2021.

Microsoft's history of developing operating systems for servers goes back to Windows NT 3.1 Advanced Server. Windows 2000 Server is the first OS to include Active Directory, DNS Server, DHCP Server, and Group Policy.
