Security News > 2024 > May > Microsoft says April Windows updates break VPN connections
Microsoft has confirmed that the April 2024 Windows security updates break VPN connections across client and server platforms.
The company explains on the Windows health dashboard that "Windows devices might face VPN connection failures after installing the April 2024 security update or the April 2024 non-security preview update."
The list of affected Windows versions includes Windows 11, Windows 10, and Windows Server 2008 and later.
While Microsoft has yet to provide the root cause behind these VPN failures, it advised home users to use the Windows Get Help app if they need support with their personal or family accounts.
One year ago, Microsoft investigated major L2TP/IPsec VPN speed issues over Wi-Fi connections on Windows 11 systems after installing the April 2023 non-security updates.
In mid-January 2022, the company also released emergency out-of-band updates to address L2TP VPN issues when connecting via the Windows VPN client after installing the January 2022 Patch Tuesday updates.
