Microsoft is changing the release schedule for the Server versions of its Windows operating system to more closely match those of the OS's desktop version and the Office suite. The roughly-every-leap-year cycle seen in the Windows Server 2008, Server 2012, and Server 2016 versions is giving way to semi-annual releases. New versions of Windows Server will come each spring and fall. The company says the more frequent updates will allow the OS to better keep pace with the ever-changing requirements of datacenter environments.
