Credit: Microsoft Microsoft is investigating reports of the latest April Windows 11 update breaking some VPN apps for users. The update, titled KB5036893, introduced several improvements to Windows 11—unfortunately it also seems to have broken VPN apps that run off a TPM-backed certificate. The exact issue users are running into seems to be with the VPN being unable to find the certificate that it needs to be used with the Extensible Authentication Protocol, Reddit User Flo-TPG explains. Now that Microsoft has confirmed it knows about the issue and is investigating it, we’ll hopefully have a fix before too long. Unfortunately, that doesn’t help those who might be trying to use a VPN with Windows 11 currently.

If you have installed update KB5036893, then the only real option you have is to uninstall it and downgrade to the previous Windows 11 version. How to uninstall a Windows 11 update If you ever have any issues with a new Windows 11 update, you can always roll back to the previous version thanks to a handy built-in system Microsoft has included in the operating system. Once the update finishes uninstalling, your system will restart, and you’ll launch back on the older version of Windows 11. Keep in mind that downgrading from some of the larger updates for Windows 11 may remove some features from your operating system.
