Good evening friends! Microsoft has released new preview builds of Windows 11 (version 22H2) under the numbers 22621.450 and 22622.450 (KB5015890) for members of the Windows Insider Beta Program.

  • Assembly 22622.450 – testing of new functions is available.
  • Assembly 22621.450 – new features are disabled by default.

If you are in a group with features disabled by default (build 22621.xxx), then check for updates and agree to install an optional update that will make these features available (build 22622.xxx).

Full build numbers:

  • 10.0.22621.450.ni_release_svc_prod2.220723-2016
  • 10.0.22622.450.ni_release_svc_prod2.220723-2016

  • Enhanced capabilities of Microsoft Defender for Endpoint to detect and intercept ransomware and advanced attacks.
  •  File compression now occurs regardless of file size if Server Message Block (SMB) Compression is configured.
  • Improved storage replication that occurs on low bandwidth networks or congested Wide Area Networks (WANs).
  • We fixed an issue that could cause Windows to display tablet mode features on non-touch devices.
