Windows 10 Servicing and Support

Windows 10 feature updates arrive through multiple servicing branches with different support policies.

To remain supported on a version Windows 10 for longer than about 18 months, customers running Windows 10 Enterprise edition can opt to follow a Long-Term Servicing Branch (LTSB) that offers long-term support similar to the Mainstream and Extended support periods offered with earlier versions of Windows. On this servicing branch, feature upgrades are deferred for the duration of support for the LTSB build.

Most users in an organization will typically be on the Current Branch for Business (CBB). This servicing branch allows organizations running Windows 10 Pro and Windows 10 Enterprise with Software Assurance a way to defer feature upgrades for approximately four months. Each CBB will retain support and the ability to defer the next set of feature upgrades for at least eight months.

The Current Branch (CB, not shown) is intended particularly for smaller organizations and consumers, and for a small set of an organization’s users who test the latest release before it becomes the CBB. This servicing branch gets feature upgrades several times per year, and these feature upgrades cannot be deferred.
