Windows devices may experience login failures after installing the April 2024 Security Update », indicated the American company in a ticket recognizing a glitch, April 30. Two weeks later, things are back to normal: May 14, a fix is made available public.

This update addresses a known issue that could cause your connection to a VPN to fail. This issue occurs after installing the April 9, 2024 update », notes Microsoft. This is not the first time that a malfunction between Windows and VPNs has been reported. In 2023, there was a performance concern.
