- Windows 11 build 22449 releases in the Dev Channel.
- Changes in the flight aren t tied to any specific release of Windows 11.
- Build 22449 introduces new boot animation, SMB compression tweaks, and settings improvements.
Microsoft is now making build 22449 accessible in the Windows Insider Program’s Dev Channel as part of the upcoming feature upgrade for Windows 11. Since this is the first preview that the firm is making available to testers in the active development branch (RS_PRERELEASE), any features or enhancements are not associated with any particular OS release.
The business claims that Windows 11 build 22449 alters the SMB compression technique that was first implemented for Windows 11 so that the file would always attempt to compress during a network transfer if compression is required.
To put it briefly, SMB compression is a feature that lets a program or user ask for files to be compressed while they are being transferred across a network. A file no longer needs to be manually compressed with an application, copied, and then uncompressed on the destination computer thanks to the new capability. Files that are compressed will use less bandwidth and transmit faster, but this comes at the expense of some extra processing power during the transmission.
Instead of an animated circle of dots, the startup will now display a progressive ring animation as part of the boot experience. (This new animation will also be used in other OS sections, according to Microsoft.)
When the machine automatically restarts to install updates, the Windows starting sound will no longer play.
The Bluetooth & Devices pages can be accessed in Quick Settings by right-clicking on the Bluetooth entry and choosing Settings.
In order to enhance discoverability, Windows 11 build 22449 now includes a new link to the touch keyboard customization settings under Typing > Touch Keyboard.
This aircraft modifies the Notification Center to enhance the visibility of app names from the notifications in the notification experience. Additionally, an acrylic background has been added to the alerts’ revised look. Additionally, an improved animation has been used in the Windows Hello message during feature setup.
Windows 11 build 22449 comes with a number of updates for the Taskbar, input, File Explorer, Settings, authentication, Bluetooth, and other areas in addition to the new internal and visual changes.

Install Windows 11 build 22449
You must use the Windows Insider Program settings from the Update & Security section to enroll your device in the Dev Channel in order to download and install Windows 11 build 22449.
After enrolling the machine in the program, click the Check for Updates button in the Windows Update settings to download build 22449. If you are new to the Windows Insider Program, however, you will need a device that satisfies the minimal system requirements in order to receive the update.
Lastly, during a clean installation, the company reiterates its warning that devices that do not satisfy the minimal criteria to test the pre-release of Windows 11 should immediately revert to Windows 10.
