<P> Enterprise licensees may use the Windows 10 Enterprise LTSB edition, where "LTSB" stands for "long - term servicing branch". LTSB milestones of Windows 10 are designed for long - term deployments in specialized environments (such as automated teller machines and medical equipment), and only receive quality of life updates (i.e. security patches). Each LTSB milestone is given a full, 10 - year support lifecycle . Due to Microsoft's intended use cases for LTSB builds, certain features, including most Cortana functionality, Microsoft Store, and bundled apps, are excluded from LTSB . Microsoft director Stella Chernyak explained that "we have businesses (that) may have mission - critical environments where we respect the fact they want to test and stabilize the environment for a long time ." Two LTSB builds have been released, correlating with the 1507 and 1607 versions of Windows 10; Microsoft stated in 2017 that the next LTSB build will be released in 2019 . </P> <P> In July 2017, Microsoft announced changes in the terminology for Windows branches, as part of its effort to unify the update cadence with that of Office 365 ProPlus and Windows Server 2016 . The branch system now defines two paces of upgrade deployment in enterprise environments, "targeted" initial deployment of a new version on selected systems immediately after its stable release for final testing, and "broad" deployment afterwards . Hence, "Current Branch" is now known as "Semi-Annual Channel (Targeted)", and "Current Branch for Business" for broad deployment is now referred to as "Semi-Annual Channel". </P> <Table> Windows 10 support and update branches <Tr> <Td> Update branch </Td> <Td> Windows Insider Preview Branch (WIPB) Beta software </Td> <Td> Semi-Annual Channel (Targeted) (formerly CB) "Consumer grade" </Td> <Td> Semi-Annual Channel (formerly CBB) "Business ready" </Td> <Td> Long - term Servicing branch (LTSB) "Mission critical" </Td> </Tr> <Tr> <Td> Edition </Td> <Td_colspan="2"> Home </Td> <Td_colspan="2"> </Td> </Tr> <Tr> <Td_colspan="3"> Pro </Td> <Td> </Td> </Tr> <Tr> <Td_colspan="3"> Education </Td> <Td> </Td> </Tr> <Tr> <Td_colspan="3"> Enterprise </Td> <Td> Enterprise LTSB </Td> </Tr> <Tr> <Td> Critical updates Security patches and stability updates </Td> <Td> Continuous as made available (choice of slow, fast, or release preview ring) </Td> <Td> Automatic and mandatory </Td> <Td> Automatic </Td> <Td> User can defer updates indefinitely </Td> </Tr> <Tr> <Td> Feature upgrades Non-critical functionality and feature updates </Td> <Td> Automatic or defer </Td> <Td> Only through LTSB in - place upgrades </Td> </Tr> <Tr> <Td> Feature upgrades cadence </Td> <Td> Continuous as released </Td> <Td> Progressively after WIPB evaluation </Td> <Td> ~ 4 months after SAC pre-evaluation or defer for an additional ~ 8 months </Td> <Td> LTSB releases are stable' snapshots' of SAC </Td> </Tr> <Tr> <Td> Upgrade support </Td> <Td_colspan="2"> Continuous updating, features silently come and sometimes go with new builds </Td> <Td> Continuous updating or in - place upgrade to supported LTSB builds </Td> <Td> In - place upgrade support for the three most recent LTSB builds </Td> </Tr> <Tr> <Td> Update support </Td> <Td_colspan="2"> 10 years (or until future builds require hardware support the old device doesn't have or ~ 4 months after a missed cumulative update made into SAC .) </Td> <Td> 10 years (or ~ 8 months from deferring build upgrade or until future builds require hardware support the old device doesn't have .) </Td> <Td> 5 years mainstream + 5 years extended </Td> </Tr> <Tr> <Td> Update methods </Td> <Td_colspan="2"> Windows Update </Td> <Td> Windows Update Windows Update for Business Windows Server Update Services </Td> <Td> Windows Update for Business Windows Server Update Services </Td> </Tr> </Table> <Tr> <Td> Update branch </Td> <Td> Windows Insider Preview Branch (WIPB) Beta software </Td> <Td> Semi-Annual Channel (Targeted) (formerly CB) "Consumer grade" </Td> <Td> Semi-Annual Channel (formerly CBB) "Business ready" </Td> <Td> Long - term Servicing branch (LTSB) "Mission critical" </Td> </Tr>
