Microsoft has released Windows 11 build 26220.9739 to users enrolled in the Beta channel of the Windows Insider Program. This update delivers new features and improvements to the operating system preview environment.

Context and Background
This release continues Microsoft's regular cadence of preview updates for Windows 11. The company frequently uses the Insider Program to test new functionality. Testers receive builds that may contain unstable or incomplete features.
As Threat Times reported on 2026-10-16, earlier Insider builds introduced refined Gaming Task View and a redesigned Run dialog. Those updates targeted the Experimental Preview channel. The current Beta channel release represents a more stable tier of testing.
Microsoft also previewed a new Search experience and a Battery Status widget in October 2026 Insider builds. Those features were part of the broader testing effort. Build 26220.9739 adds to this ongoing cycle of development and refinement.
Who Is Affected
Users enrolled in the Windows Insider Program Beta channel are the primary recipients of this update. These participants opt into receiving preview versions of the operating system. They accept the risk of encountering bugs or performance issues.
General consumers who have not joined the Insider Program will not receive this build. Microsoft restricts these preview updates to registered testers. This ensures that unstable code does not reach production devices.
Enterprise users should monitor official channels for stable release schedules. Beta builds are not intended for production environments. Organizations typically wait for general availability before deploying updates.

What to do and how to stay safe: Microsoft
- Verify your Windows Insider channel enrollment if you wish to receive preview builds.
