Windows is having problems with some VPNs after the latest update, but you can fix it

The latest Windows update is causing problems with VPNs and in some cases preventing the connection from being established.

Regardless of the Microsoft operating system you use, it seems that in no case are you free from any update causing problems. We have the last example with the most recent update that has come to Windows 10 and Windows 11 and that is preventing the connection of some VPNs.

At the moment it has been detected that this update prevent connection in some cases to the VPN tool of the operating system, but also to third parties such as SonicWall, Cisco and WatchGuard Firewalls, as reported in TechRadar.

Even if from Microsoft has not yet been reported about the situation, on social networks like Reddit several users tell their experiences and there are those who begin to share how it can be solved.

The updates that are having problems are the last two that have been added to these operating systems: KB5009543 on Windows 10 and KB5009566 on Windows 11.

As for how to fix it, if you can’t connect to your VPN after the latest OS update… At the moment you only have the option to remove patches that have been added with it. Even if can be risky.

In TechRadar they report that it can be done through the command prompt using the corresponding command depending on your version of Windows:

Windows 10: wusa /uninstall /kb:5009543

Windows 11: wusa /uninstall /kb:5009566

But we point out that this is a measure that we only recommend in situations where it is urgent to connect because it also opens the door for your operating system to suffer major security vulnerabilities.

In any case, if you’re not in a hurry, It’s best to wait for Microsoft to fix it.. The news on the subject has jumped in the last hours and it is most likely that they will begin to solve it soon.
