Microsoft Releases Windows 11 Insider Builds 26120.6780 (Beta) and 26220.6780 (Dev): Copilot+ Gets Smarter, Settings Go Interactive

Microsoft’s Windows Insider Program continues its push toward refining the next versions of Windows 11 Insider Builds with back-to-back releases in the Beta and Dev Channels. On October 10, 2025, Microsoft unveiled two parallel builds—Build 26120.6780 (Beta) and Build 26220.6780 (Dev)—both under update KB5067103.

While both builds share much of the same feature set, they cater to different tracks: the Beta Channel focuses on the upcoming Windows 11 version 24H2, while the Dev Channel looks ahead to 25H2. The updates bring deeper Copilot+ integration, interactive system settings powered by AI, new design polish, and important bug fixes for everyday features like File Explorer and the Start menu.

Smarter Settings with the New “Agent in Settings”

Both builds introduce a powerful redesign in Agent in Settings, available for Copilot+ PCs. This smart agent streamlines the process of modifying system preferences, integrating contextual AI-powered recommendations directly into the Settings interface.

Windows now offers a “Recommended Settings” card that suggests quick configuration tweaks based on recent activity. The experience has been rebuilt for efficiency—users can make changes inline without navigating away. For instance, if you recently modified display brightness or network preferences, the Settings homepage now surfaces those recent actions for quick access.

The search experience in Settings also gets an upgrade. When users type queries like “increase volume,” the search flyout shows not only more relevant results but actionable controls. If a setting is maxed out, Windows now provides a contextual dialog explaining the limit and offering an adjustment slider—making Settings far more conversational and intelligent.

Drag Tray Evolves for Sharing and File Movement

The Drag Tray—a newer UI element introduced earlier this year—continues to mature. Both Dev and Beta builds now support multi-file sharing, intelligently surfacing appropriate apps and locations for each file. For example, drag-and-dropping multiple images may suggest apps like Paint, Teams, or WhatsApp, while documents may recommend moving or copying to OneDrive or local folders.

This small but impactful feature enhances Windows 11’s desktop multitasking, positioning it closer to mobile OS sharing workflows.

“Click to Do” Preview: A Glimpse into Context-Aware Productivity

Another intriguing addition for Copilot+ PCs is Click to Do (Preview), an experimental feature that shows Microsoft’s direction toward contextual computing. This feature highlights actionable items—emails, tables, or text—in apps you’re using.

Users can click on these highlighted elements to perform smart actions directly, such as summarizing an email, extracting data from a table, or initiating a response. It’s part of Microsoft’s larger vision for AI-augmented Windows experiences, where the operating system responds proactively to your tasks instead of passively waiting for clicks.

Microsoft also notes that visual cues have been refined for clarity, making it easier to notice which items are interactive.

Enhanced Security and Visual Consistency

Security-conscious users will appreciate the return of Administrator Protection in the Windows Security settings, specifically under Account Protection. This toggle gives admins greater control over system modifications, serving as a defensive layer against unauthorized privilege escalation attempts.

Microsoft also continues refining visual consistency across the OS, introducing Dark Mode updates for legacy components. This week’s builds expand dark mode to the Run dialog (Win + R), aligning it with modern Fluent Design elements. The rollout is gradual, meaning not every Insider will see it immediately, but this expansion indicates continued progress toward a unified design language in Windows 11.

OneDrive Integration Gets a Refresh

A subtle but notable design change is appearing across both Insider channels: the new OneDrive icon in the Settings app. Found in the Accounts and Homepages sections, the refreshed icon reflects Microsoft’s modern Fluent UI and ties better into the look of Windows 365, Edge, and Microsoft 365 product branding.

This change may seem minor, but it demonstrates how Microsoft is steadily modernizing even small visual details to unify its product ecosystem ahead of the next major Windows release cycle.

Fixes for Everyday Windows Experience

Both builds include a large set of bug fixes that will be appreciated by Insiders frustrated by recent issues in earlier flights:

• File Explorer: Crashes that previously plagued some users are now resolved. The stability improvement should make browsing and file management smoother, especially for those syncing with cloud drives.

• Start Menu: Touchscreen users can once again interact with right-click context menus without dismissal. Scrolling glitches that returned to the top unexpectedly have been corrected.

• Taskbar and System Tray: Shortcut cycling using WIN + (number) is back to working as intended, improving keyboard-driven window switching.

• Search: An issue where unexpected text or random symbols appeared instead of search results has been fixed.

• Click to Do (Preview): Fixed visual offset issues for gesture-based activation on multi-monitor setups.

Known Issues to Watch

While refinements are steady, a few known issues persist:

• Taskbar previews animations are temporarily disabled due to interference with the “share window” feature.

• File Explorer dark mode bugs: Copy progress dialogs may flicker or display a misplaced white block when zoomed or scaled.

• Xbox Controller bugcheck: A long-running Bluetooth conflict remains unresolved for some. Microsoft advises users to manually remove the problematic XboxGameControllerDriver.inf file in Device Manager to prevent blue screens.

These issues underscore why Insider participation remains vital—Windows engineers rely on community feedback before wider rollout.

Dev vs Beta: What These Builds Mean for Windows 11 Users

Although feature parity between the Beta (26120.6780) and Dev (26220.6780) builds is striking, the distinction lies in their release trajectory.

For users enrolled in the Beta Channel, these updates are closer to what the next public version of Windows 11 might look like. Meanwhile, Dev Channel users get access to cutting-edge features sooner, but with a higher risk of instability.

The enablement package system—first introduced with Windows 10—continues to play a vital role in how Microsoft delivers these updates efficiently across builds.

Windows 11’s Path Forward

Taken together, these builds point toward Microsoft’s next leap in making Windows 11 more intelligent, responsive, and personal. The fusion of Copilot+ features, AI-powered Settings, and smarter contextual actions like Click to Do illustrate Microsoft’s ongoing mission to make the OS think alongside its users rather than act merely as a tool.

For Windows 11 users outside the Insider program, these previews provide a glimpse of the near future—one where every click, drag, and command is augmented by a layer of intelligence that understands and adapts to individual workflows.

As Microsoft continues to refine these innovations through Controlled Feature Rollouts (CFR), wider release in 2026 seems likely. These enhancements make Windows 11 not just a modern OS, but a platform that learns from how people use it.
