With the January 2022 Windows update release many VPNs have stopped working. They wont connect.

The fix is to either upgrade to Windows 11, run a Microsoft hot fix or remove the patch.


Removing teh patch needs consideration because it fixes various vulnerabilities however it breaks the VPN.


To remove the patch:


  1. click on the Windows button
  2. type cmd
  3. right click on “Command Prompt” and select Run as administrator
  4. type “wusa /uninstall /kb:5009543
  5. follow the instructions.

We have a video here showing the process:
