Microsoft has started work on the major Windows 11 release expected in the second half of 2022, and Windows 11 Build 22449 is now available to Windows Insider’s Dev Channel members. This build is the first Insider build for the upcoming major update.
If you have a supported device on the Development Channel, you may see a new update titled “Windows 11 Insider Preview 22449. 1000 (rs_prerelease)”. The final version of the Windows 11 operating system is now almost ready and will begin rolling out to everyone on October 5. This update shows that Microsoft has started making improvements for future versions.
Build 22449 is not tied to any particular version. However, some features and improvements in these builds are expected to be available to users with Windows 11 version 22H2 (codenamed Copper) in the second half of 2022.
Finally, it’s worth noting that Dev Channel builds will be more problematic than builds currently on the Beta Channel. If you want to stay on Windows 11 version 21H2 (Build 22000), you can immediately switch to the Beta Channel or leave the Windows Insider Program.
With Windows 11 Build 22449. 1000, there are significant changes, and without further ado, let’s take a closer look at them.
Changes in SMB Compression Feature
SMB compression was first introduced in Windows Server 2022 and Windows 11. This feature allows an administrator, user, or application to compress files while transferring them over the network. Compressed files will slightly increase CPU usage during transfers, but will reduce network usage and transfer time will drop significantly.
Based on testing and analysis, Microsoft has made changes to the way the default compression feature works. Previously, the SMB compression algorithm tried to compress the first 524.288.000 bytes (500MB) of a file during transmission, taking into account at least 104,857,600-byte-frequent (100MB) files compressed between these 500MB files. For example, if less than 100 MB was compressed, SMB was not working on the rest of the file.
With Build 22449, this algorithm completely changes. Instead, it can be applied to all files when compression is desired.
