What’s new on Windows 11 update 26220.9223 (Beta)
These are the new features and improvements rolling out in the Beta channel:
A simpler way to open apps maximized
Windows 11 is also removing a small but annoying bit of friction with a new “Open apps maximized” accessibility setting.

When you enable the feature, the system automatically maximizes apps as they launch, which can be especially useful with screen readers, magnification, tablet use, or simply for anyone who prefers a consistent full-screen workspace.
The option is known as “Open apps maximized,” and it’s available under Settings > Accessibility > Visual effects.
Other changes
In addition, the company fixed several problems with the release of build 26220.9223:
- Microsoft Store: Packaged WinUI 3 apps that require elevation can now support in-app purchases through Microsoft’s integrated commerce platform.
