Windows 11 Insider Beta Preview Build 26220.9492

Release date: 18 September 2026

Changes and improvements

We're improving Live Captions with a new Include Screen Reader audio setting, which is off by default. With the setting off, Live Captions won't transcribe audio from screen readers such as Narrator, JAWS, and NVDA, keeping captions focused on microphone and system audio.

Fixed an issue where some applications that used HCS-managed virtual machines experienced issues when sharing host folders with Linux VMs using Plan9. Folders shared from the Windows host using Plan9 didn't appear or couldn't be accessed in the guest environment.

Fixed an issue where backing up using File History unexpectedly failed with an error saying, "No usable drives found."

Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.9492).

Features and experiences included in these builds might never get released as we try out different concepts and get feedback. Features might change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.
Some features in active development we preview with Windows Insiders might not be fully localized, and localization will happen over time as features are finalized. As you see issues with localization in your language, report those issues to us via Feedback Hub.
