Windows 10 Servicing and Support

Windows 10 became available in volume licensing on Aug. 1, 2015. It is the current version of the Windows Client OS for desktop, laptop, and tablet computers.

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 service branch, feature upgrades are deferred for the duration of support for the LTSB build.

The Current Branch for Business (CBB) allows organizations running Windows 10 Pro, and Windows 10 Enterprise with Software Assurance, a way to defer feature upgrades for up to four months and retain support of the deployment of a particular CBB build (deferring additional feature upgrades) for at least eight months.

Intended particularly for smaller organizations and consumers, the Current Branch (CB) gets feature upgrades several times per year and these feature upgrades cannot be deferred.

A new build of Windows 10 was released to computers on the CB on Nov. 12, 2015. (This build was sometimes previously referred to as Threshold 2 and is labeled TH2 in the illustration.)
