Microsoft fixes VPN issues caused by September Windows updates
BLUF
Microsoft resolved a known Windows update issue that prevented Always On VPN from connecting properly.
NEWS
The problem appeared after installing the September 2026 Windows 11 security updates and affected Always On VPN connectivity. Microsoft has now released a fix for the issue, addressing the regression introduced by those updates.
Why I Care
Organizations and remote workers that rely on Always On VPN may have experienced dropped or failed connections after patching. This matters because VPN failures can block secure access to corporate resources and disrupt business operations.
Next Steps
IT administrators should deploy Microsoft's latest Windows 11 update containing the fix, prioritize affected devices, and test Always On VPN connectivity after patching. End users experiencing issues should install the latest available Windows update and reconnect their VPN.
