Build 26220.5770 (KB5064093) for Windows 11 25H2 brings new features (Dev)

Windows 11 build 26220.5770 (KB5064093) introduces Click to Do Excel table actions, an on-screen Braille viewer, and improvements to Windows Share.
The build is available in the Dev Channel, with similar features in Beta (build 26120.5770), and the 25H2 enablement package is now live in Release Preview.

As part of the version 25H2 development, Microsoft is rolling out Windows 11 build 26220.5770 (KB5064093) in the Dev Channel of the Windows Insider Program. This update brings new features for Click to Do, introduces on-screen Braille, and improves the Windows Share experience.

You will also notice that the company is updating the build number to “26220” instead of the previous “26200,” but this change is only for the Dev Channel, as version 25H2 will be released with the 26200 series build number.

In addition, on August 29, 2025, Microsoft is also making available Windows 11 25H2 in the Release Preview Channel as build 26200.5074 (KB5064081) as an enablement package for version 24H2 that will flip the switch to change the version number to 25H2.

Furthermore, in the Beta Channel, Insiders can now download the Windows 11 build 26120.5770 (KB5064089) for version 24H2, which includes the same changes as build 26220.5770 from the Dev Channel.

The option is currently available for Copilot+ PCs featuring the Qualcomm Snapdragon processor. In addition, you’ll need the latest version of Excel available with a Microsoft 365 subscription. Microsoft also notes that this feature is still not available for users in Europe.

Click to Do is also adding the “View Microsoft 365 Profile Cards” action that brings up a card with the person’s information from the organization or school when hovering over any of their information visible in a snapshot.

On-screen Braille for Windows 11

This flight also introduces a new “Braille viewer” feature as part of the Windows Narrator, which allows you to view an on-screen textual and Braille representation of the output for teaching purposes.

If you want to launch the feature, use the “Windows key + Ctrl + Enter” keyboard shortcut to open the Windows Narrator features, and use the “Narrator key + Alt + B” shortcut to open Braille.

Microsoft notes that you also need to configure Windows Narrator for Braille output, which requires downloading a package from Settings > Accessibility > Narrator > Use a Braille display with Narrator.

Windows Share find app option

When using the “Windows Share” interface to share a file, you can now use the “Find apps” option to select the app that you want to use. Additionally, when searching, if the app isn’t available, you can download it directly from the Microsoft Store.
