Windows 11 Insider Beta Preview Build 26220.9223

Release date: 21 August 2026

Changes and improvements

[Accessibility]

A simpler way to open apps maximized

  • We're introducing a new accessibility setting, Open apps maximized, that automatically maximizes app windows when they open, so you no longer have to do it yourself every time. This small change removes a bit of everyday friction, whether you use a screen reader or magnification, work in tablet mode, or simply prefer a consistent, full-screen workspace.

  • To turn it on, go to Settings > Accessibility > Visual effects, and turn on Open apps maximized. Once enabled, Windows maximizes app windows for you as they open. Give it a try, and let us know how it works for you.

[Microsoft Store]

  • This update provides support for in-app purchases in packaged WinUI 3 apps that require elevation, helping developers offer purchases through Microsoft's integrated commerce platform.

Reminders for Windows Insiders in the Beta Channel

  • Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.9223).

  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.

  • 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.
