Microsoft Pushes New Windows 11 Insider Builds for 26H1, Adds WinRE Wi-Fi Support
Beta and Experimental channels get personalization tweaks, Emoji 17.0, and a major enterprise recovery upgrade.
Microsoft just rolled out new Insider Preview builds for Windows 11, version 26H1. If you are on the Beta or Experimental channel, you are looking at Build 28020.2818 and Build 28120.2824 respectively. The biggest headline is not a flashy UI gimmick. It is a quiet, enterprise-grade upgrade to Windows Recovery Environment networking that finally lets WinRE hop onto saved Wi-Fi profiles without manual credential entry.
The 26H1 track itself is a bit of an anomaly in Microsoft's annual cadence. Announced in February, it is a targeted platform release built specifically to support the upcoming Qualcomm Snapdragon X2 processors. It is not an upgrade path for existing 24H2 or 25H2 machines, and it will not crossgrade to the 26H2 feature update later this year. However, at the same time, Microsoft is juggling multiple Insider tracks right now. On the exact same day it ships 26H1 updates, 25H2 is getting its own Beta flight, and 26H2 just landed in the Release Preview channel back on August 27 with ISOs dropping today.
WinRE Finally Gets Wi-Fi Without the Manual Grind
For years, the recovery environment has been a Wi-Fi black hole. You would boot into a cloud rebuild or quick machine recovery and immediately hit a wall if your network required WPA2 or WPA3. Previously, WinRE could only auto-connect to wired unauthenticated Ethernet or networks explicitly preconfigured for recovery. Now, it can automatically reuse eligible Wi-Fi profiles saved in the main Windows OS, including certificate-based networks. The capability is enabled by default, though IT admins can still toggle it off via policy. It is a small change on paper, but for anyone who has stood over a struggling corporate laptop trying to hand-enter a Wi-Fi password at the recovery prompt, it is a massive quality-of-life upgrade.
Polished Backgrounds, New Emojis, and a Missing Print Tool
Most of the rest of this flight lands in the polish bucket. The Personalization background page is more reliable, DIB image files are finally supported as desktop wallpapers, and the black-screen wallpaper bug that appeared after every reboot in the previous flight has been fixed. Slideshow wallpapers no longer force a return to static images when you add a second desktop, and previews now render correctly on portrait monitors. File Explorer Home preserves your expanded and collapsed section state going forward, which aligns with the broader context menu and reliability push Microsoft outlined on August 17. The Magnifier toolbar got a visual refresh with updated icons and tighter padding, while Read Aloud and zoom controls stay exactly as they were.
There is a notable absence in this build. The modernized Print Management tool has been temporarily yanked while Microsoft works through feedback. It is the kind of pullback that usually signals a rough beta, but since the legacy tools remain fully functional, it is not going to leave anyone in the lurch. Taskbar reliability improvements made it to the Beta channel, and the modern Run dialog got a first-launch stability tweak on Experimental. Nothing earth-shattering, but the synchronized content across both channels suggests Microsoft is finally tightening the gap between them.
You can grab Build 28020.2818 through the Beta channel and Build 28120.2824 via Experimental. The full change logs live on Microsoft's Learn site, and the Flight Hub has up-to-date tracking for every active Windows 11 branch. If you are rolling the 26H2 Release Preview ISO, that is available separately starting today.
