What's new in Windows 11 build 22449 (Dev channel)

  • SMB compression , available 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. More details here.
  • The boot screen now shows a progressive ring animation.Progressring Indeterminate
  • Right-clicking on the Bluetooth entry in Quick Settings and selecting Settings will now open the main Bluetooth & Devices page in Settings.

Those include CPUs with an embedded TPM, support for secure boot, and support VBS and specific VBS capabilities. The generic hardware requirements include >1GHz, 2-core processors, 4GB memory, and 64GB of storage.


Microsoft noted that if TPM 2.0 and CPU family/model criteria are missing, such devices will continue to receive new builds, but some of the new features may stop working or behave incorrectly.

Finally, if the device fails to meet the requirements beyond TPM 2.0 and CPU family, it will have a limited exception to preview Windows 11 builds until general availability on October 5, 2021.
