Microsoft rolled out Windows 11 Insider Preview Build 26220.5770 to the Dev Channel on August 29, packing a handful of productivity and accessibility upgrades that put AI-driven text actions and a long-awaited Braille viewer into testers’ hands. The flight is notable not only for what it adds but for how it changes the build numbering scheme, marking a jump from the 26200 series to 26220 for Dev-specific releases. While the new features—led by Click to Do’s Convert to Table and Microsoft 365 profile card integration—promise to streamline workflows, early adopters face hardware and licensing gates, plus a handful of driver-level gremlins that Microsoft has already documented.

Click to Do Gets Real Work Done: Convert to Table with Excel

The headliner in this build is a practical extension of Click to Do’s on-screen capture smarts: the ability to recognize simple tabular data and send it directly into Microsoft Excel. Dubbed “Convert to table with Excel,” the feature aims to eliminate the tedious manual retyping of meeting whiteboard photos, receipts, or static lists embedded in documents. Invoke Click to Do (Win + Click, Win + Q, or a touch swipe), select the table region, and choose the action—the system detects the structure and exports the data to a new Excel worksheet.

Microsoft is positioning this as a time-saver for knowledge workers, analysts, and students who frequently grab data from screenshots. But the fine print tempers the excitement. Early access is locked to Copilot+ PCs running Snapdragon processors; Intel and AMD Copilot+ machines will gain support “soon,” with no specific date given. Additionally, the feature demands the latest version of the Microsoft Excel app and an active Microsoft 365 subscription. Table detection is explicitly marked as an early preview, so expect rough edges and improving accuracy in subsequent flights.

Microsoft 365 Profile Cards Surface Inside Click to Do

A subtler but strategically important addition is the integration of Microsoft 365 Live Persona cards within Click to Do. Now, when the feature detects an email address, clicking it displays a full profile card with contact information, recent collaboration context, and quick actions like calling or messaging. The card pulls data from your work or school account (Entra ID required), effectively turning Click to Do into a lightweight organizational assistant that reduces the need to switch into Outlook or Teams.

Microsoft is notably keeping this capability away from European Economic Area (EEA) Insiders for now, citing regional considerations. The company’s phased rollout approach means that even eligible Dev Channel users might not see the profile cards immediately—toggle-gated features are enabled for subsets of devices, a pattern repeated across recent builds.

Accessibility Takes Center Stage: Braille Viewer for Narrator

One of the largest single-build accessibility investments in months arrives as a new Braille viewer within Narrator. Designed primarily for sighted teachers, assistive technology trainers, and testers, the viewer mirrors the output of a connected refreshable Braille display in an on-screen window, showing both Braille dots and translated text. It launches via the Narrator key + Alt + B shortcut and updates in real time, supporting varying cell counts.

This fills a long-standing gap where non-Braille readers could not easily follow what a student or user was reading on a Braille display. Microsoft encourages Insiders to file feedback via the Feedback Hub for any missing behavior, as the viewer remains in preview.

The Windows share window receives a “Find Apps” field that lets you search locally installed applications and browse Microsoft Store suggestions without leaving the sharing surface. It’s a small ergonomic win that reduces friction when sending content to an app you don’t regularly pin to the top of the share list. This change aligns with other recent share improvements, such as app pinning and a simplified UI, collectively making daily interactions more fluid.

Fixes You Can Appreciate and Known Issues to Watch

Build 26220.5770 isn’t all features; it delivers a healthy batch of fixes for nagging bugs. Taskbar and system tray corrections prevent the date/time flyout from opening on the wrong monitor and eliminate duplicate thumbnail previews on hover. An explorer.exe crash triggered by ALT + Tab in earlier flights has been squashed, and a display bug that silently disabled HDR is now resolved for affected testers.

Known issues, however, remind us this is still a Dev Channel build. Microsoft flags two problems with detailed workarounds:
- Audio driver borkage: Some Insiders are reporting audio loss after updating, with Device Manager showing yellow exclamation marks on devices like “ACPI Audio Compositor.” The recovery path involves manually updating the driver through Device Manager.
- Xbox controller blue screens: Using an Xbox controller over Bluetooth can trigger bugchecks on certain hardware configurations. Microsoft offers a driver uninstall procedure for the offending OEM driver entry.

Additionally, File Explorer may show shared items in Home even when none exist, and the Temporary Files scan in Settings can get stuck. Both are under investigation.

Cross-Channel Context and Rollout Caveats

This flight continues the established Dev/Beta divergence: Dev sits on the 25H2 development track (build string 26220.xxxx) while Beta remains on 24H2 (26120.xxxx). Earlier August builds—26200.5761 and 26200.5751—laid groundwork with Click to Do selection refinements and cross-device resume experiments. Microsoft’s Controlled Feature Rollout model means even with the “Get the latest updates as they are available” toggle enabled, not every Insider will receive all new features at once. This staged approach limits blast radius but can create confusion when features appear to work for some and not others.

IT professionals should treat Dev builds as experimental lab material. Copilot+ features, including Convert to Table, carry hardware and license prerequisites that must be factored into procurement and testing plans. Privacy-conscious organizations should audit the cloud callouts that Click to Do’s Microsoft 365 integrations introduce, particularly regarding telemetry and data residency.

How to Approach This Build Now

For power users keen to try the new capabilities, install the flight on a secondary machine or VM. Enable the “latest features” toggle if you want the highest chance of seeing staged additions, but be ready to file feedback. To test Convert to Table, ensure you’re on a Snapdragon Copilot+ PC, have the latest Excel app, and hold a Microsoft 365 subscription. Invoke Click to Do on a simple on-screen table, select the region, choose “Convert to table with Excel,” and verify the data lands correctly.

If you hit the audio or controller bugs, follow Microsoft’s posted recovery steps exactly, and create a system restore point before tinkering with drivers. For enterprise testers, lab validation of drivers (audio, Bluetooth, GPU) is non-negotiable before broader pilot rings.

What Comes Next

Microsoft’s cadence suggests more small, high-value features in the coming weeks rather than a single massive feature dump. Expect improved table detection accuracy, broader Copilot+ hardware support for Convert to Table, incremental accessibility updates, and continued polish of the share interface. The company’s commitment to controlled rollouts and telemetry-driven iteration means patience is required, but the direction is clear: Windows 11 is becoming a more connected, AI-savvy platform that ties on-screen content directly into productivity apps.

For now, Build 26220.5770 is a worthwhile playground for Insiders with the right hardware, offering a taste of how AI-powered capture can evolve from a gimmick into a daily workhorse.
