Microsoft has released Windows 11 Insider Preview Build 22449 to the dev channel.

Announcing Windows 11 Insider Preview Build 22449

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 22449 to the Dev Channel.

You may notice that this build number is higher than the Windows 11 preview builds you’ve been receiving. That’s because we’re moving the Dev Channel back to receiving builds from our active development branch (RS_PRERELEASE). This means the builds released to the Dev Channel no longer match the Windows 11 experience  that will be released to customers on October 5th.

These builds are from the earliest stage in a new development cycle with the latest work-in-progress code from our engineers. These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds while flighting in the Dev Channel. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight. Because of being at the earliest stage of a new development cycle, you won’t see new features or major changes in these builds right away. These builds are also not matched to a specific release. New features and OS improvements from these builds could show up in future Windows releases  when they’re ready, and we may deliver them as full OS updates or servicing releases.

For those of you who are new to the Windows Insider Program and flighting of OS updates –  check out this article for how flighting works and what to expect in each of our channels.
