Windows 11 KB5006674 applies to the the RTM version. This brings the build to 22000.258.
- 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.
If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
