Windows Update Fixes Always On VPN Bug but Introduces New Connectivity Issues

Microsoft has released cumulative updates KB5127646 and KB5127648 to resolve a critical bug in its 'Always On VPN' feature, which previously caused connection failures on Windows 11 24H2 and newer systems. The bug often left users unprotected by failing to establish secure connections upon internet detection. While some users report that the patch has unexpectedly improved VPN stability and speeds, others are experiencing significant new connectivity problems. Specifically, reports indicate that the update has disrupted WPA2-Enterprise (802.1X/PEAP) wireless network authentication, preventing clients from connecting to corporate WiFi networks. Microsoft has suggested a temporary workaround for VPN issues by switching to single-protocol profiles, but the new authentication bugs remain a concern for IT administrators. As the company investigates these unintended consequences, users are advised to monitor for further patches to address the ongoing network instability.
