Today’s Beta‑channel drop from the Windows Insider team continues the 24H2 servicing stream with a focused, polish‑first update that blends new Copilot+ experiences, accessibility improvements, and a raft of targeted fixes — Windows 11 Insider Preview Build 26120.5770 (KB5064089) is now available to Beta Channel Insiders running Windows 11, version 24H2.
Background / Overview
Microsoft’s Beta Channel for Windows 11, version 24H2, operates as the near‑final proving ground for features that may ship broadly; updates are delivered as enablement‑style 26120.xxxx builds and are often split into two deployment buckets: features being
gradually rolled out to Insiders who opt into the “get the latest updates” toggle, and
fixes/features deployed to all Beta devices that successfully install the cumulative package. This release model gives Microsoft the agility to test Copilot‑driven experiences at scale while minimizing the blast radius for regressions. (
