Launch cmd.exe & and an other .exe with a python script

Hi,

here is my problem : I would like to launch a window of a command prompt (see image 1), and put a specific line of command in it (which corresponds to "cmdLine" in the code). I know it's possible to use "system(cmdLine)" to execute the command, however when I do this, my Command Window on matlab is 'locked' (see image 2, I cannot launch the last command, which is "taskkill -f -im emprogui.exe"). That's why I would like to put the "cmdLine" command into a different window so I could be able to still use my Command Window.

Here is the code :

EMProPath = "D:\Keysight\EMPro2020Py3\win32_64\bin\empro.exe";
projectPath = "C:\Users\Myname\Desktop\Test\EMPRO\Model";
pythonPath = strcat("C:\Users\Myname\Desktop\Test\EMPRO\python_script_t.py");

cmdLine = strcat('"', EMProPath, '" "',projectPath, '" --bootscript="', pythonPath, '"');
system(cmdLine); % Need to be changed to use a cmd prompt instead of the Command Window of Matlab, I know that 'system("cmd.exe &")' 
                 % opens a command prompt separately, so it might be looking close to something like this I guess (or not at all) :
                 % system(strcat("cmd.exe & ", cmdLine))

pause(10)

system('taskkill -f -im emprogui.exe')

(Image 1)

(Image 2, last line is added manually, but it doesn't work)
