Windows 11 Insider Previews: What’s in the latest build?

The Windows 11 2023 Update has been released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out public preview builds to members of its Windows Insider Program, allowing them to test out — and even help shape — upcoming features.

Skip to the builds

The Windows Insider program is divided into four channels:

The Canary Channel is where platform changes (such as major updates to the Windows kernel and new APIs) are previewed. These changes are not tied to a particular Windows release and may never ship at all. Little documentation is provided, and builds are likely to be very unstable. This channel is best for highly technical users.

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 and Release Preview Channels also receive bug-fix builds for the currently shipping version of Windows 11. See “How to preview and deploy Windows 10 and 11 updates” for more details about the four channels and how to switch to a different channel.

Not everyone can participate in the Windows 11 Insider program, because the new operating system has more stringent system requirements than Windows 10. If your PC fails to meet the minimum hardware requirements for Windows 11, you cannot join the Windows 11 Insider Program. (See “How to check if your PC can run Windows 11.”)

Below you’ll find information about the Windows 11 preview builds that have been announced by Microsoft in the past six months. (For the Release Preview Channel, we cover builds released for the current version of Windows 11, not for earlier versions.) 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.

Note: If you’re looking for information about updates being rolled out to all Windows 11 users, not previews for Windows Insiders, see “Windows 11: A guide to the updates.”

The latest Windows 11 Insider preview builds

Windows 11 Insider Preview Build 26120.1930

Release date: October 4, 2024

Released to: Dev Channel

In this build, those in the Dev Channel who have turned the toggle on to receive the latest updates get a small set of general improvements and one bug fix, for a bug in which the boot menu wasn’t displaying correctly for some Insiders with dual-boot devices.

Everyone in the Dev Channel can now configure the Copilot key. You can have the Copilot key launch an app that is MSIX packaged and signed, increasing security and privacy.

There are two known issues in this build, including one in which if you click or tap on a letter on Start menu’s All apps list, the list may break. If you encounter this issue, please try rebooting or restarting explorer.exe to fix it.

Windows 11 Insider Preview Build 22635.4300 

Release date: October 4, 2024

Released to: Beta Channel

In this build, those in the Beta Channel who have turned the toggle on to receive the latest updates as soon as they are available will see “All” instead of “All apps” on the Start menu. In addition, Windows Search runs IFilters in the Less Privileged App Containers (LPACs). LPACs are like app containers, but they deny even more permissions by default. The intent is that a process running in a LPAC has access only to the resources needed by it. This helps to minimize the potential damage that can be caused by a compromised process by limiting its access to sensitive system components and data.

Two bugs are fixed for those who have turned the toggle on to receive the latest updates as soon as possible, including one in which items in the navigation pane became very spread out for some people.

There are two known issues in the build, including one in which live captions will crash if you try to use them.

Several bugs have been fixed, including one in which the emoji panel closed when you tried to switch to the kaomoji and symbols sections, or after selecting an emoji, and another in which the Widgets icon sometimes unexpectedly displayed twice in the taskbar.

There are three known issues in this build, including one for those using Copilot+ PCs, in which If you are joining the Canary Channel from the Dev Channel, Release Preview Channel or retail, you will lose Windows Hello pin and biometrics to sign into your PC; you’ll see error 0xd0000225 and an error message “Something went wrong, and your PIN isn’t available.” You should be able to re-create your PIN by clicking “Set up my PIN.”

There is one known issue in this build: if you click or tap on a letter on Start menu’s All apps list, the All apps list may break. If you encounter this issue, try rebooting or restarting explorer.exe to fix it.

​The Windows 11 2023 Update has been released, but behind the scenes, Microsoft is constantly working to improve the newest version of Windows. The company frequently rolls out public preview builds to members of its Windows Insider Program, allowing them to test out — and even help shape — upcoming features.

Skip to the builds

The Windows Insider program is divided into four channels:

The Canary Channel is where platform changes (such as major updates to the Windows kernel and new APIs) are previewed. These changes are not tied to a particular Windows release and may never ship at all. Little documentation is provided, and builds are likely to be very unstable. This channel is best for highly technical users.

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 and Release Preview Channels also receive bug-fix builds for the currently shipping version of Windows 11. See “How to preview and deploy Windows 10 and 11 updates” for more details about the four channels and how to switch to a different channel.

Not everyone can participate in the Windows 11 Insider program, because the new operating system has more stringent system requirements than Windows 10. If your PC fails to meet the minimum hardware requirements for Windows 11, you cannot join the Windows 11 Insider Program. (See “How to check if your PC can run Windows 11.”)

Below you’ll find information about the Windows 11 preview builds that have been announced by Microsoft in the past six months. (For the Release Preview Channel, we cover builds released for the current version of Windows 11, not for earlier versions.) 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.

Note: If you’re looking for information about updates being rolled out to all Windows 11 users, not previews for Windows Insiders, see “Windows 11: A guide to the updates.”

The intent is that a process running in a LPAC has access only to the resources needed by it. This helps to minimize the potential damage that can be caused by a compromised process by limiting its access to sensitive system components and data.

Two bugs are fixed for those who have turned the toggle on to receive the latest updates as soon as possible, including one in which items in the navigation pane became very spread out for some people.
