I'd try giving popen() a go, like so:

var_dump(popen('notepad','r'));

It looks like using popen on windows will still wait for the child program to exit: https://www.php.net/manual/en/function.popen.php#92413 – Samuel Aug 04 '21 at 22:10

The problem you are running into is PHP won't stop executing until it's sub-processes have quit. Notepad.exe won't quit until you manually close it so php will never stop running until it times out.

If you are trying to launch the program into the background on Windows so that PHP won't wait for it you can use the Windows start /b command

exec("start /b notepad");
