Microsoft's October 2026 Windows updates, KB5127648 and KB5127646, failed to fix a persistent 'Always On VPN' connection problem despite initial claims that they would, leaving the issue unresolved as of October 20, 2026. This ongoing technical glitch impacts Windows 11 users who rely on stable VPN connections for work.

This continuous problem means IT administrators and businesses still face disruptions in secure remote access for employees using Windows 11 devices. The initial false announcement of a fix by Microsoft created confusion and wasted efforts for those trying to restore critical network access.
