I didn't know about run, thanks for the tip. However when I use it to
launch something from the Start Menu Run command, it still pops open a

Windows has a flag set in each EXE as to whether or not it is a console
or GUI program. There are tools that can set the flag in a given EXE file.
It's not a flag, it's an exported function.
If a program exports winmain(), it's a gui program, if it exports main(), it's
a console program.
No. It really is a flag.
See
https://docs.microsoft.com/en-us/windows/desktop/debug/pe-format#windows-subsystem
You are describing the behaviour of (recent versions of) the Microsoft
linker, which guesses the default value of this flag based on what
symbols are defined
See
https://docs.microsoft.com/en-us/cpp/build/reference/entry-entry-point-symbol,
specifically the sentence "If the /DLL or /SUBSYSTEM option is not
specified, the linker selects a subsystem and entry point depending on
whether main or WinMain is defined."
