Windows 11 Build 22449 is now available with new loading animation

Microsoft has begun work on the major Windows 11 release
expected to land in the second half of 2022 and Windows 11
Build 22449 is now rolling out to supported PCs in the Dev
Channel of the Windows Insider program. It’s the first test
build from the company’s active development branch internally
known as “Nickel”.

If you have a supported device in the Dev Channel, you will get
a new patch titled “Windows 11 Insider Preview 22449.1000
(rs_prerelease)”. As mentioned, it is from the active
development branch, so Windows 11 Build 22449 number is higher
than the preview builds you’ve been receiving in Dev or Beta

What’s happening here is that the development of Windows 11 has
reached the point where its first public build is almost due
and Microsoft has begun work on Windows 11 upcoming features,
releasing an initial build to supported PCs in the Dev Channel
of the Insider program.

The build 22449 is from the active development branch
(RS_PRERELEASE) and it is not tied to any particular release.
However, it is likely that some of the features and
improvements included in these builds will ship to the
consumers in the second half of 2022 with Windows 11 version
22H2 (codenamed Copper).

For those unaware, the codenames of these Windows update
release semesters is based on the corresponding element in the
periodic table. At the moment, we’re getting builds from a
development branch currently codenamed “Nickel”, but this
is temporary and these changes will eventually appear in
Windows 11 22H2 codenamed “Copper”.

The highlighted elements in the above table represent the
following development branch/version:

  • Windows 11 version 21H2 (shipping on October 5) = Cobalt
  • Windows 11 Nickel (Ni) branch (not tied to any specific
  • Windows 11 version 22H2 (shipping in October of 2022) =
    Copper (Cu).

Dev Channel builds will be buggier than the builds currently
available in the Beta Channel. If you wish to remain on Windows
11 version 21H2 (Build 22000), immediately switch to the Beta
Channel or opt out of the Windows Insider Program.

So what are the major changes in Windows 11 Build 22449.1000?
Well, there’s nothing huge here. That’s because the build is
from the earliest stage in the company’s development cycle and
users won’t see major changes at the moment.

Features and Improvements in Windows 11 Build 22449

The first update from the Nickel branch directly affects the
SMB compression behaviour. For those unaware, SMB compression
is a feature that allows enterprises and apps to request
compression of files when they transfer over the network.

Currently, MB compression would compress the first 500MiB of a
file during transfer and it will stop working if fewer than 100
Mib were compressible. This behaviour has changed with the
update rolling out today and Microsoft will now always attempt
to compress the rest of the file.

A new loading animation for Windows

Microsoft is experimenting with a new WinUI-compliant
progressive ring animation for the operating system. This will
replace the existing animated circle of dots on loading
screens, and similar improvements will soon begin rolling out
to other areas of the operating system.

Build 22449 comes with one change to the Windows startup sound.
After the update, Windows will no longer play startup sound
after a scheduled update is applied and your device reboots
when you are not actively using it.

Likewise, the notification center is getting some minor
improvements. The notification toasts now have an acrylic
background and Bluetooth entry in Quick Settings now opens the
main Bluetooth settings if you right-click on it and select

The notification center design has been adjusted and apps will
now appear visually separated to create a floating experience.

Windows 11 Build 22449 comes several other improvements:

  • Microsoft is expanding rounded corners to the Windows
    Sandbox dialog.
  • The Focus Assist in the notification center has been
    updated with accessibility improvements.
  • Calendar flyout will update automatically when you modify
    the time format or add additional clocks.
  • Explorer.exe is now more reliable when the taskbar is
    pinned across multiple monitors.
  • Microsoft has fixed an issue where an angry looking emoji
    will be suggested when you search for sad emoji in the emoji
  • Microsoft has addressed several crashes or deadlocks when
    accessing Start, Search, and emoji panel.
  • Microsoft has updated the Typing > Touch Keyboard page
    in the Settings app to include a link to the touch keyboard
    personalization page.
