Windows 11 730 Published by

Microsoft has rolled out Windows 11 Insider Preview Build 26220.7859 to Windows Insiders in the Beta Channel with several tweaks that most users won't notice unless they've enabled insider builds on their system. The new build includes improvements such as updated account settings for Microsoft 365 Family subscribers, a fix for taskbar icon glitches, and a solution to the file explorer jump bug. Nearby sharing has also been upgraded to handle large files more reliably over slower Wi-Fi networks, eliminating stalls and timeouts. Additionally, Bluetooth wheel settings are now more stable, preventing drivers from resetting scroll wheels to default speeds after updates.



Windows 11 Insider Preview Build 26220.7859 – What’s New for Beta Insiders

The latest Beta‑channel preview adds a handful of tweaks that most users will notice only if they’ve already turned on the “receive insider builds as they arrive” switch in Settings > Windows Update. This article breaks down each change, points out which ones actually matter, and flags the bits that feel more like polishing than a real feature drop.

New Account Settings Tweaks

Microsoft 365 Family subscribers now see an upgrade prompt on the Accounts page of the Settings app. The option appears right under the subscription card and lets you jump to a different plan without opening a browser. If the banner is annoying, the same page hosts a “suggested content” toggle that can be flipped off, removing the prompt entirely. In practice the change saves a few clicks for people who were already hunting through the Microsoft Store for a better deal, but it’s not going to overhaul how most users manage their accounts.

Taskbar Icon Glitch Gets Fixed

Insiders have reported phantom icons hanging around the system tray when the taskbar was set to auto‑hide. The new build tightens up the logic that decides whether an icon should stay visible, so the tray now stays truly empty until something needs your attention. I’ve seen the old behavior cause confusion during screen recordings – the missing icons looked like a bug in the video editor rather than Windows itself.

File Explorer Jump Bug Squashed

A particularly nasty issue caused all open Explorer windows and tabs to suddenly leap to the Desktop or Home view, wiping out whatever folder you were working in. The fix restores the expected behavior: each window remembers its last location unless you explicitly navigate elsewhere. Users who keep dozens of tabs open for research will finally stop losing their place mid‑session.

Nearby Sharing Gains Stamina

Sending large files over nearby sharing used to stall after a few megabytes, especially on slower Wi‑Fi networks. The update improves the reliability of the underlying transfer protocol, so big videos now make it across without timing out. I’ve watched coworkers stare at a half‑sent 2 GB file for minutes; this should cut that waiting time down dramatically.

Bluetooth Wheel Settings More Stable

The wheel settings under Settings > Bluetooth & Devices were prone to resetting after a driver update, leaving scroll wheels acting like they’re stuck in “slow mode.” The new code adds extra validation when the page loads, preventing the UI from flipping back to defaults on its own. If you’ve ever been forced to re‑calibrate your mouse every few weeks, this will feel like a small but welcome relief.

That’s the gist of what insiders can expect from build 26220.7859. As always, keep the feedback loop open in Feedback Hub – it’s the fastest way to push any lingering quirks back into Microsoft’s queue.
