Windows 11 has officially launched today, and Microsoft has complemented its release with a new support page that details its earliest known issues. They comprise compatibility issues between the new operating system and Oracle VirtualBox, Cốc Cốc (a Vietnamese web browser), and Intel’s Killer networking software.

The latter is probably noteworthy for anyone who uses Intel’s Killer networking products, as it has the potential to slow down video streaming, online gaming, and other online activities that might rely on the UDP protocol. Intel began offering Killer products such as the Wi-Fi 6 AX1650 after acquiring owner Rivet Networks in 2020.

Here’s the bug description, per Microsoft:

Compatibility issues have been found between some Intel “Killer” networking software and Windows 11. Devices with the affected software might drop User Datagram Protocol (UDP) packets under certain conditions. This creates performance and other problems for protocols based on UDP. For example, some websites might load slower than others in affected devices, with videos streaming slower in certain resolutions. VPN solutions based on UDP might also be slower.

Microsoft says that it is already working on a solution. The fix is expected to be available as part of the October security update, which is scheduled for release next week on October 12, 2021.

  1. I think it’s interesting that the folks who made sure they were updated and got in early didn’t seem to have these same issues.

  2. I wonder what’s different between W11 and W10 drivers for that – as most everything for W10 carries right over with no issue.
