How to prevent the launch of the second copy of the application in Windows?

Question

Windows

There is a program that will just run a second copy of itself. How can the system hide the launch of the second of the same process?

Answer 1

Write a driver that will prohibit the launch of any processes from a given one and rejoice. The OS itself, as far as I know, has neither the need nor the ability to do so.

Answer 2

more than one employee sins with this ... Maybe there is a parameter in the properties of the shortcut that would prohibit the launch of the second copy
