This approach worked for me, I combined it with another code to find my window, and worked just fine, thank you. I am looking for a window named "outlook", bring it forward then maximize.

 # maximize window
top_windows = []
win32gui.EnumWindows(windowEnumerationHandler, top_windows)
for i in top_windows:
    if "outlook" in i[1].lower():
        print(i)
        hwnd = win32gui.GetForegroundWindow()
        win32gui.ShowWindow(hwnd, win32con.SW_MAXIMIZE)
        break

You need the HWND of the window that you want to maximize. 'C:/Desktop/UD.ca' is not an HWND. Think of it as a unique ID for a window.

As an example, you can get the HWND of the foreground window by 

hwnd = win32gui.GetForegroundWindow()

and then pass that in the call to ShowWindow,

win32gui.ShowWindow(hwnd, win32con.SW_MAXIMIZE)

If you want to search all visible Windows for one that contains a title, see Get HWND of each Window?
