Windows Server, formerly known as Windows NT Server, is a series of operating systems created by Microsoft, first released in 1991 with "Windows NT 3.1 Advanced Server". As the name suggests, these are the server variations of Microsoft Windows, and are intended for mission critical tasks.
Stable releases of Windows Server are typically every 3-4 years, and versions of Windows Server are typically supported for about 10 years. Certain versions of Windows Server allow users to purchase a paid support plan which will extend the updates by up to 4 years. This plan is included with Microsoft Azure purchases.
