Where other Windows 10 servicing models push feature upgrades to customers every six months,(LTSC) LTSB does so only every two or three years. That means fewer changes during a set timeline, a less-involved upgrade effort, and fewer disruptions as well as fewer possibilities for applications breaking because of a modification of the OS.

Windows Server Long-Term Servicing Channel (LTSC):
The Long-term Servicing Channel is the release model you’re already familiar with (currently called the “Long-term Servicing Branch”) where a new major version of Windows Server is released every 2-3 years. Users are entitled to 5 years of mainstream support, 5 years of extended support, and optionally 6 more years with Premium Assurance. This channel is appropriate for systems that require a longer servicing option and functional stability.

Windows 10, version 1809 makes it easier to deploy updates, stay current, and better protect your data and devices end to end. Quickly deploy corporate images to new or existing devices. Manage corporate-owned and user-owned devices in the cloud, on premises, or using a combination of both.
