False positive when detecting Virtual Machine

I am testing an app that I developed and when I enter a key I get

The function failed because this instance of your program is running inside a virtual machine / hypervisor and you've prevented the function from running inside a VM

but I am not running in a VM.

What can I do?

Running on Windows 10.

Check if you have Hyper-v running. If yes then you _are_ running in a VM.

How can I check that?

Sorry, I was passing by on a weekend day so I decided to help out with an unanswered LimeLM question (I don't work for Wyday). However, I don't feel that doing Windows support is appropriate for me or this site. I'm sure Google would be great for answering your last question.
