How to protect my application such a way that no one could make it portable?

Good day!
I have a question about the portability of applications. How to protect my application such a way that no one could make it portable?

What a weird question... Why would you want to do that? And also, what System should your application run on?

Or am I misunderstandin g your question and you want to make sure nobody can install it on a usb drive and use it on different computers?

Use a dongle. A USB device supplied by you with the software. You embed something like a GUID and compile for each user. Then on startup the program looks for the dongle which has the matching GUID. If the match is not found or if the dongle is not attached, the program does not start.

Thanks for the answers
1. It's not just about portability on a USB flash drive. It's about virtualization
2. There are programs to intercept keys.

Why is it necessary for you? What is the purpose? You want to have a connection with the developed programs or something like that?

I need a permanent connection to monitor my applications
