Linker error, undefined reference - winapi

Question

I am an absolute beginner. This is my first C++ code. Taking from the default project in Dev C++, youtube tutorials, and some intuition, I came up with the simple code below. I know the answer is going to be easy. I just can't seem to paste together answers from other posts the fix for mine. Any help you provide is GREATLY appreciated!!!
I get "undefined reference to CreateProcessWithLogonW" error.

According to the documentation, CreateProcessWithLogonW is defined in Advapi32.lib. You need to pass that library to the linker.
