Windows 11 Build 22449: New boot logo animation, SMB compression + TONS of FIXES!

Hands-on with the Windows 11 Insider Preview build 22449

Microsoft has just announced the release of the Windows 11 Insider Preview build 22449 for Insiders in the Dev channel. Starting today, Dev Channel Insiders will receive Windows 11 builds coming from the active development branch (RS_PRERELEASE).

Therefore, you may see and get your hands-on the new experimental features that won’t arrive in the first version on Windows 11 coming to consumers on October 5, 2021.

WHAT’S NEW IN BUILD 22449?
SMB compression behavior change
● We first introduced SMB compression in Windows Server 2022 & Windows 11. SMB compression allows an administrator, user, or application to request compression of files as they transfer over the network. This removes the need to first deflate a file manually with an application, copy it, then inflate on the destination PC. Compressed files will consume less network bandwidth and take less time to transfer, at the cost of slightly increased CPU usage during transfers.

Based on testing and analysis, we have changed the default behavior of compression. Previously, the SMB compression decision algorithm would attempt to compress the first 524,288,000 bytes (500MiB) of a file during transfer and track that at least 104,857,600 bytes (100MiB) compressed within that 500-MB range. If fewer than 100 MiB were compressible, SMB compression stopped trying to compress the rest of the file. If at least 100 MiB compressed, SMB compression attempted to compress the rest of the file. This meant that very large files with compressible data – for instance, a multi-gigabyte virtual machine disk – were likely to compress but a relatively small file – even a very compressible one – would not compress.

Starting in Build 22449, we will no longer use this decision algorithm by default. Instead, if compression is requested, we will always attempt to compress. If you wish to modify this new behavior to return to a decision algorithm, please see this article: Understanding and controlling compression behaviors.

CHANGES AND IMPROVEMENTS:
● 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.
Progressive ring animation
● 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.
● Adjusted the design of Notification Center to make the app names more visibly separated from the notifications.

FIXES:
[Taskbar]
● If your Taskbar is set to auto-hide, hovering over the Taskbar corner or bottom of secondary monitors should now properly invoke the Taskbar.
● Fixed an issue that could make the calendar flyout get in a state where only the week names would load and not the calendar part.
● Addressed an issue where the lunar calendar would get out of sync with the actual date in the calendar flyout.
● If you’ve updated your time format, additional clocks added to the calendar flyout will now update to reflect that.
● Hovering over one of the Desktops in the Task View flyout should no longer unexpectedly change your active Desktop.
● The Focus Assist button in Notification Center now has an accessible name for screen readers.
● Fixed an underlying issue that was causing the font in the Taskbar previews to not be correct.
● Did some work to help make explorer.exe more reliable when using the Taskbar on multiple monitors.
