How do I know I have A VPN?

[DekuReptile]

I have worried that I have a VPN working in the background of my laptop. It keeps on saying its detecting a VPN I have on my laptop and I couldn't find any trace of having one. I have tried to search it up and try the methods they said online to see if I had one but none of them work for me. I would like to know if I have a VPN and want uninstall it. I need help soon

Thank you,
