General-purpose Surface devices running Long-Term Servicing Branch (LTSB) are not supported. As a general guideline, if a Surface device runs productivity software, such as Microsoft Office, it is a general-purpose device that does not qualify for LTSB and should instead run Current Branch (CB) or Current Branch for Business (CBB).
For more information about the servicing branches, see Overview of Windows as a service.
LTSB prevents Surface devices from receiving critical Windows 10 feature updates and certain non-security servicing updates. Customers with poor experiences using Surface devices in the LTSB configuration will be instructed to upgrade to CB or CBB. Furthermore, the Windows 10 Enterprise LTSB edition removes core features of Surface devices, including seamless inking and touch-friendly applications. It does not contain key in-box applications including Microsoft Edge, OneNote, Calendar or Camera. Therefore, productivity is impacted and functionality is limited. LTSB is not supported as a suitable servicing solution for general-purpose Surface devices.
General-purpose Surface devices are intended to run CB or CBB to receive full servicing and firmware updates and forward compatibility with the introduction of new Surface features. With CB, feature updates are available as soon as Microsoft releases them. Customers in the CBB servicing model receive the same build of Windows 10 as those in CB, at a later date.
Surface devices in specialized scenarios–such as PCs that control medical equipment, point-of-sale systems, and ATMs–may consider the use of LTSB. These special-purpose systems typically perform a single task and do not require feature updates as frequently as other devices in the organization.
