cmd terminal

[Raysz]

So I have the simple program
that I made in Python tkinter

It opens up a cmd window and executes sfc /scannow

What I'm trying to figure out is if I click on the X at the top right corner
I get a ^C how do I prevent this, how do I close the window the proper way


I tried to put it in a try block with a keyboard interruption and that didn't seem to work
I tried several different ways to use kill but I am unclear on how it's supposed to work

def sfc_scannow():
    # sfc / scannow
    if not pyuac.isUserAdmin():
        statusbar.set('Access is denied, you are not an admin')
        root.after(5000, lambda: statusbar.set(''))
        # print('okM')  # for testing
    else:
        sfc_scannow_data()
        


def sfc_scannow_data():
    subprocess.Popen("start /wait sfc /scannow", shell=True)
