Microsoft is investigating reports that the latest April Windows 11 update breaks some VPN apps for users. The update, named KB5036893, introduces several improvements to Windows 11, and unfortunately, it also appears to break VPN apps running TPM-enabled certificates.
Reddit user Flo-TPG explains that the exact issue users are experiencing appears to be that the VPN is unable to find the certificate for use with the Extensible Authentication Protocol. Now that Microsoft has confirmed that it's aware of the issue and is investigating it, we hope a solution will be found soon.
Unfortunately, this won't help those who may currently be trying to use a VPN on Windows 11. If you have update KB5036893 installed, your only real option is to uninstall it and downgrade to a previous Windows 11 version.
How to uninstall Windows 11 updates
If you encounter any problems with the new Windows 11 updates, you can always roll back to the previous version, thanks to the convenient built-in system Microsoft has included in the operating system.
First, open the Settings menu on your Windows 11 PC.
Navigate to Windows Update .
Now click on Update History .
Scroll all the way to the bottom and select "Uninstall updates."
Find the update you need to uninstall (in this case, you need to look for update KB5036893 ) and click Uninstall , then complete the process.
Once the update has finished uninstalling, your system will reboot and you will be restarting the older version of Windows 11. Keep in mind that downgrading from some larger updates to Windows 11 may remove certain features in the operating system.
