I tried to unistall the #KB5009543 from command line (run as Administator) in Win10
wusa /uninstall /kb:5009543
But the update isn't unistalled, as it says the update is important!!
Any workaround???
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I'm now getting this error trying to connect to VPN on Windows 11: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.
I've noticed this on 2 Windows 11 laptops (one personal and another for work). Both have been updated today and no longer able to connect to a couple VPNs.

Anyone else? Anyone know how to fix it other than uninstalling the update?
