## Why It Matters
Windows 10 Version 1511 is an identifiable milestone in the Windows 10 release sequence because it represents a formal, named update cycle (the "November Update"/"Threshold 2") following the initial 1507 release. As a published software version it served as the platform for a series of cumulative builds and designated stable releases across late 2015 and early 2016, as indicated by explicit build-version dates. Knowing this version is important for IT administrators, support personnel, and users who must track compatibility, update history, and support lifecycle for devices running Windows 10. The documented discontinuation date (2017-10-10) signals the end of official lifecycle for this version, which matters for security patch planning and migration decisions. In release management and historical tracking, Version 1511 sits between the original release (1507) and the later Anniversary Update (1607), making it part of the early evolution of Windows 10's servicing and versioning model.
