Trouble connecting to your VPN? Microsoft admits that a recent Windows security update is preventing virtual connections

A recent Windows security update is causing some VPN connections to fail, Microsoft has said. The company is working on a resolution.

The KB5036893 update, known as the April security update, was first released on April 9, 2024. Since then, and after rolling out across heaps of PCs, Microsoft has noticed the inadvertent effect the update is having on virtual private networks. It's causing some of them to fail to connect entirely, thus potentially leaving users without a way to hide their IP address or change their location on the web.
