Right-clicking on the Bluetooth entry in Quick Settings and selecting Settings will now open the main Bluetooth & Devices page in Settings.Please use the Feedback Hub to give feedback or report issues with SMB compression, using the Files, Folders, and Online Storage > File Sharing category. If you wish to modify this new behavior to return to a decision algorithm, please see this article: Understanding and controlling compression behaviors. Instead, if compression is requested, we will always attempt to compress. Starting in Build 22449, we will no longer use this decision algorithm by default. 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. If at least 100 MiB compressed, SMB compression attempted to compress the rest of the file. If fewer than 100 MiB were compressible, SMB compression stopped trying to compress the rest of the file. 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. Compressed files will consume less network bandwidth and take less time to transfer, at the cost of slightly increased CPU usage during transfers.īased on testing and analysis, we have changed the default behavior of compression. This removes the need to first deflate a file manually with an application, copy it, then inflate on the destination PC. SMB compression allows an administrator, user, or application to request compression of files as they transfer over the network. We first introduced SMB compression in Windows Server 2022 & Windows 11. What’s new in Build 22449 SMB compression behavior change

Microsoft has also recommended insiders to check the known issues list as these new builds may have more bugs and issues. The Build 22440 brings many UI changes including new boot screen animation, acrylic background for notifications, notification center design changes and more.
