Microsoft has shipped four new Windows 11 Insider Preview builds today alongside a welcome policy change for testers who prefer clean installs. Starting now, ISOs will be available to download alongside every regularly scheduled build across all versions of the Beta and Experimental channels. Previously, ISO availability was inconsistent across channels, which made reinstalls and fresh installs harder than they needed to be.
To find ISOs for any current Windows Insider Preview build, head to the Windows Insider Preview Downloads page.
Today’s Builds
Four builds went out today across the channel lineup. Beta Channel lands on Build 26220.8340. Experimental Channel (including Dev Channel) is at Build 26300.8346. Experimental 26H1, which now includes Canary 28000 series devices, is at Build 28020.1921. Experimental Future Platforms, covering the 29500 series, is at Build 29580.1000.
The 28000 series Canary devices are also beginning to move to Experimental 26H1 today. Microsoft notes this doesn’t change the version of Windows on your device, just the channel experience they’re on.
What’s New
The headline feature in today’s builds is a refreshed Run dialog, rolling out as an opt-in on the Experimental channel. The updated design brings a cleaner look and new controls accessible from Settings, General, Advanced. It’s a small but long-overdue polish pass on one of Windows’ oldest UI elements.
Widgets gets a quieter default configuration. Microsoft is testing new defaults that turn off Open on hover and taskbar badging, reducing interruptions for users who find the Widgets panel intrusive. Users who want proactive updates can turn those features back on through Widgets settings.
The Feedback Hub also gets a meaningful update in version 2.2604.301.0. The file upload limit for feedback submissions is back up to 500MB, upvote and comment counts are more accurate, community feedback for non-English users can now be switched to English, and collection titles and official responses will be automatically translated in major languages.
For the full release notes for your specific channel, Microsoft has them available at the Windows Insider Blog. You can also check our coverage of last month’s five-build release day for context on how the new channel system works.
