Microsoft is rolling out Windows 11 Insider Preview Build 26220.6780 (KB5067103) to the Dev Channel, and while it’s not a massive update, it does include one highly requested tweak — dark mode for the classic Run dialog.
This build continues Microsoft’s steady push toward UI consistency, polishing older system components to better match Windows 11’s modern aesthetic. Alongside that, the update delivers a handful of useful fixes and small improvements for Insiders.
🆕 What’s New in Windows 11 Build 26220.6780
🌑 Run Dialog Finally Gets Dark Mode
After years of mismatched visuals, the Run box (Win + R) now respects your system theme. The change is rolling out very slowly, so only a subset of Insiders will see it immediately, with broader availability planned for future builds.
💡 Click to Do (Preview) Enhancements
On Copilot+ PCs, the Click to Do experience now highlights key on-screen elements — such as tables, emails, or buttons — making it easier to discover actions powered by AI.
Administrator Protection Returns
The Administrator Protection toggle is back in Windows Security > Account Protection. This setting helps safeguard local admin accounts from unauthorized access and tampering.
Refreshed OneDrive Icon
Microsoft is also introducing a redesigned OneDrive icon that now appears across Settings > Accounts and on the main Settings homepage. It’s a small visual change, but one that aligns with the OS’s evolving design language.
Bug Fixes and Improvements
The new build focuses heavily on reliability and crash prevention. Here’s what’s been fixed:
- Click to Do (Preview): Fixed an issue where swiping from the right edge on the primary display showed the gesture animation on the wrong monitor.
- Taskbar & System Tray: Pressing
WIN + numberrepeatedly now correctly cycles through open app windows. - File Explorer: Fixed frequent crashes that some Insiders experienced in the previous flight.
- Start Menu: Addressed unwanted scrolling and a touch bug that caused context menus to close immediately.
- Search: Corrected instances of unexpected or placeholder text appearing in search results.
- App Stability: Resolved a major issue that caused several applications (including browsers) to crash unexpectedly.
Availability and Rollout
Windows 11 Build 26220.6780 is now available to all Dev Channel Insiders. Some changes may appear early for users who enable the “Get the latest updates as soon as they’re available” toggle under Settings > Windows Update.
The dark Run dialog remains on a gradual rollout, meaning it may take a few more flights before reaching everyone.
Final Thoughts
While this isn’t a game-changing release, it’s a solid one. The dark Run dialog may seem minor, but it’s symbolic of Microsoft’s ongoing effort to modernize every corner of Windows 11 — even the legacy ones. Combined with multiple fixes and small UI updates, Build 26220.6780 keeps refining the OS ahead of future feature expansions in upcoming Dev builds.
