Windows Server 2016 Servicing by Install Mode

Of the two servicing options available for Windows Server 2016, Desktop Experience and Nano Server are each limited to one, but both are available for Server Core installations. The servicing options, called channels, determine how often new features are delivered and how long each version is supported.

The Long-Term Servicing Channel (LTSC) is required for Windows Server 2016 with Desktop Experience and is an option for Server Core. The LTSC will deliver security updates and critical bug fixes monthly or more frequently. Systems on an LTSC version are eligible for five years of Mainstream support and five years of Extended support. New features are delivered with subsequent LTSC versions, expected roughly every two to three years. Organizations require new licenses or must maintain Software Assurance (SA) to obtain later LTSC versions. LTSC allows businesses that have licensed Windows Server to defer new features until their deployed LTSC versions leave Extended support. This can benefit systems where stability and application compatibility are critical.
