Key notes

  • If you thought that Patch Tuesday was only for Windows 10, Microsoft just proved you wrong. 
  • Apparently, the company was planning on a much larger release during this month's event.
  • Companies still using Windows 7 also received exclusive security patches, as paying customers.
  • And, for all this to be complete, the new OS also received its very first cumulative update.
W11 KB

Windows 11 KB5006674 is now available for devices running Microsoft’s latest operating system. So, also taking into consideration this cumulative update, the build number right now is 22000.258.

Redmond officials said that it also addresses known compatibility issues between some Intel Killer and SmartByte networking software and Windows 11.

Windows 11 gets its very first cumulative update

Usually, Windows Updates released on Tuesday include security fixes, but the first patch for Windows 11 is all about compatibility fixes.

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.

The best part about this first Windows 11 KB is that it doesn’t come with any known issues. So either there’s really nothing wrong with it, or the problem is so deeply embedded that it’s going to take a while to find it.

Microsoft is also releasing Windows 11 servicing stack update 22000.190, with the following release note:

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.

The first Windows 11 cumulative update is available via Windows Update and Microsoft Update, Windows Update for Business, Microsoft Update Catalog, and Windows Server Update Services (WSUS).
