Microsoft releases a new Windows 11 build, but this time it has been limited to Windows Insiders in the Dev Channel. That’s because Microsoft is now moving the Dev Channel back to receiving builds from the active development branch (RS_PRERELEASE) and thus it will no longer match the Windows 11 experience that's going to release on October 5th.


The latest Windows 11 Insider Preview Build 22449 comes with a change in the SMB compression behavior. It also adds a long list of other changes, improvements and bug fixes. If you are on the Dev Channel, upgrade to this build now.

What’s new in Windows 11 Build 22449

SMB compression is a new feature which was first introduced in Windows Server 2022 & Windows 11. It allows an administrator, user, or application to request compression of files as they transfer over the network. This feature consumes less network bandwidth and take less time to transfer.


Starting with Windows 11 Build 22449, the system will attempt to compress the data if the compression is requested by any media.



Changes and Improvements in Windows 11 Build 22449

  • The boot screen now shows a progressive ring animation for loading the OS instead of an animated circle of dots. We are working to replace this animated circle of dots in other areas of the OS over time.
  • Right-clicking on the Bluetooth entry in Quick Settings and selecting Settings will now open the main Bluetooth & Devices page in Settings.
  • The Windows startup sound will no longer play after an unattended update (aka a scheduled Windows update when you are not at your PC).
  • Added a link to the touch keyboard personalization settings from Typing > Touch Keyboard to help improve discoverability.
  • Notifications now have an acrylic background.
  • Updated animation used in the notification introducing you to Windows Hello if it hasn’t been set up.
  • Updated the dialog when closing Windows Sandbox so that it has rounded visuals.
