    This Update KB5009543 needs to be addressed by Microsoft ASAP.

    We need a patch to fix this update. This update has crippled mine and may other companies. VPN during Covid is an essential service. Microsoft better get their Collective S--t together and fix it now. Uninstalling this update from over 100 users is taking up a lot of essential IT resources. 

    Where is the patch?

    Please stop pushing out update KB5009543 for Windows 10 since it breaks VPN protocol on all Windows 10 computers! There is a problem with this update!
