It’s patch Tuesday and Microsoft have released the first update to Windows 11 since the OS was released last week. KB5006674 takes the release build to 22000.258 from 22000.194 and contains the following changes:

  • Addresses known compatibility issues between some Intel “Killer” and “SmartByte” networking software and Windows 11 (original release). Devices with the affected software might drop User Datagram Protocol (UDP) packets under certain conditions. This creates performance and other issues for protocols based on UDP. For example, some websites might load slower than others on the affected devices, which might cause videos to stream slower in certain resolutions. VPN solutions based on UDP might also be slower.

Windows 10 21H1 has also had an update via KB5006670.  There is still no news on when 21H2 of Windows 11 will ship, that is currently being tested by Windows Insiders not running Windows 11.
