The company is actively investigating the issues and promises a forthcoming update that should resolve the problems introduced by the April update. Until then, users experiencing severe disruptions are advised to uninstall the problematic update if possible​​.

Impact on Users

The VPN issues have caused considerable inconvenience, impeding the ability of businesses and individuals to securely connect to remote networks. For many, this disruption has hampered productivity, highlighting the critical role that stable VPN connections play in today’s interconnected work environments.

Steps for Users Experiencing Issues

For those affected, Microsoft suggests several temporary solutions while they work on a more permanent fix. Users can revert to a previous version of Windows 11 or temporarily disable certain settings that might be exacerbating the issue. Detailed guidance is available through Microsoft’s support channels.

As Microsoft works on patching this issue, users are advised to keep their systems updated and follow the official Windows Release Health dashboard for the latest updates. The resolution to these VPN problems is expected soon, aiming to restore full functionality and security to affected systems.
