KB5006674 Security Patch Windows 11 OS Build 22000.258

Microsoft releases a new cumulative update for Windows 11 i.e. KB5006674 that upgrades the existing OS Build to 22000.258. Since this is a security patch, it primarily deals with improving the existing conditions of the Update components, built-in services, and a few others. 


KB5006674 Changelog

Here are the key changes on this security patch update for Windows 11 –

  • Improves the security of all Windows components and Microsoft services.
  • Resolves known compatibility issues between some Intel “Killer” and “SmartByte” networking software and Windows 11 (original release). The devices that have the affected software simply drop User Datagram Protocol (UDP) packets under certain conditions. Due to this, several users notice performance as well as other issues for protocols based on UDP. As a result, these issues were occurring –
    • Some sites load faster while others take a huge time to even get to the first contentful paint.
    • If you stream or watch videos, the playback would be in lower resolutions. 
    • VPN solutions based on UDP might also be slower.
