Microsoft releases KB5006674 update for Windows 11 to fix networking problems and more

It's now a week since Microsoft started the rollout of Windows 11, and the latest version of the operating system has just received its first cumulative patch.

With the release of the KB5006674 update, Microsoft is addressing one of the compatibility issues that was preventing some people from upgrading to Windows 11. Taking the Windows 11 version number up to 22000.258, the update fixes issues found between the operating system and some Intel networking software.

Announcing the availability of the update, Microsoft explains its purpose: "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".

Microsoft also points out that the update also improves the Windows 11 servicing stack:

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

KB5006674 is available to download via Windows Update, from the  Microsoft Update Catalog website, or by using Windows Server Update Services (WSUS).
