A method that prohibits others from using a piece of software on the machine

How can I prevent others from using your software? Set access rights? Encrypt the folder?

There is a way to compare "loss"~

Create a new text file in the folder where the main program is located;

Rename the file to "ws2_32.dll".

Now execute your software and see if it can be used? At runtime, you will be prompted: "The application or DLL X:\\XXXXXXX\\WS2_32.dll is an invalid Windows image. Please check your installation disk again."

Let's see what this ws2_32.dll is. ~
