Microsoft announced the upcoming release of Windows 11 in late June and is now releasing preview builds to some members of its Windows Insider program. The new operating system is scheduled to begin rolling out on October 5.

The Windows Insider program is divided into three channels:

  • The Dev Channel is where new features are introduced for initial testing, regardless of which Windows release they’ll eventually end up in. This channel is best for technical users and developers, and builds in it may be unstable and buggy.
  • In the Beta Channel, you’ll get more polished features that will be deployed in the next major Windows release. This channel is best for early adopters, and Microsoft says your feedback in this channel will have the most impact.
  • The Release Preview Channel typically doesn’t see action until shortly before a new feature update is rolled out. It’s meant for final testing of an upcoming release and is best for those who want the most stable builds.

The Beta Channel is currently receiving previews for the initial Windows 11 release, while the Dev Channel is testing potential features for Windows 11 updates beyond the initial October 5 release. As of Sept. 9, commercial PCs in the Release Preview Channel can receive the commercial preview of the Oct. 5 Windows 11 release. (The Release Preview Channel is also receiving builds for the next Windows 10 feature update.)

Not everyone can participate in the Windows 11 Insider program, because the new operating system has more stringent system requirements than Windows 10. As outlined in this Microsoft blog post, if your PC fails to meet the minimum hardware requirements for Windows 11, you cannot join the Dev or Beta Channels. You may instead join the Release Preview Channel for testing Windows 10 preview updates. (See our guide to Windows 10 Insider Preview builds for details about those releases.)

If you were a member of the Windows 10 Insider Dev Channel prior to June 24 and your PC doesn’t meet the hardware requirements, you can still receive Windows 11 builds for now. After Windows 11 is generally available, PCs that don’t meet the minimum requirements will not receive Windows 11 Insider Preview builds.

For each build, we've included the date of its release, which Insider channel it was released to, a summary of what’s in the build, and a link to Microsoft's announcement about it.

Release date: September 2, 2021

Released to: Dev Channel

With this build, the Dev Channel moves back to receiving only builds from the active development branch (RS_PRERELEASE).

Additionally, there are several minor changes in the build, including notifications now having acrylic backgrounds. There are also many bug fixes, including for one that caused the font in the taskbar previews to incorrect and another that crashed explorer.exe when using Alt-Tab.

File Explorer has a new command bar and new overall look, including new context menus. New themes have been added to the overall interface, and Windows sounds have been redesigned.

Widgets: Windows 11 comes with a set of resizable informational widgets for things such as news, the weather, your calendar, local traffic, a to-do list, photos from OneDrive, news, sports, and more.

Multitasking: Windows 10’s “Snap” feature that gives you control over how you can arrange your open windows gets a makeover. You can choose from pre-built Snap layouts and arrange them into predesigned Snap groups. Desktops available via Task View can now be reordered and have custom backgrounds.

Touch, inking, and voice input: The touch keyboard gets 13 new themes and can be resized. There’s also a voice typing launcher, and several new touch gestures. The build lets you quickly switch between additional languages and keyboards via a switcher that appears at the lower right on the taskbar next to Quick Settings. There’s also now a menu for customizing digital pens.

Other changes include:

  • The Microsoft Store has been redesigned. Eventually Android mobile games and apps will be housed there, and be able to work on Windows 11.
  • When you undock your laptop, the windows on your external monitor will be minimized. When you re-dock your computer to your monitor, Windows puts everything back where it was before.
  • With Windows 11’s Dynamic Refresh Rate, your PC can automatically boost the refresh rate when you’re inking or scrolling to give you a smoother experience, and lower the refresh rate when you don’t need it to save power on your laptop.
  • Settings has been redesigned, including left-hand navigation that persists between pages. There are also breadcrumbs to help you know exactly where you are in Settings.
  • Windows 11 offers Wi-Fi 6E.

Known issues: There are more than two dozen known issues in this build across a wide variety of features, including the taskbar, Settings, Start, Search, Widgets and the Store. For example, when upgrading a device with multiple user accounts to Windows 11, Settings will fail to launch; after clicking the Search icon taskbar, the Search panel may not open; and when upgrading to Windows 11 from Windows 10 or when installing an update to Windows 11, some features may be deprecated or removed.
