You need to do the following:

1. Allocate a SHACTIVATEINFO structure
2. When your main window receives a WM_SETTINGCHANGE message, call 
SHHandleWMSettingChange() passing the structure
3. When you receive WM_ACTIVATE, call SHHandleWMActivate() passing the same 

The resizing of your window will now be done for you.


class SHACTIVATEINFO(ctypes.Structure):
    _fields_ = [
        ('cbSize', DWORD),
        ('hwndLastFocus', HWND),
        ('flags', UINT),

    def __init__(self):
        self.cbSize = ctypes.sizeof(self)

    aygshell = ctypes.cdll.aygshell

    SHHandleWMSettingChange = aygshell[83]
    SHHandleWMSettingChange.argtypes = [ HWND, WPARAM, LPARAM, 
    SHHandleWMSettingChange.restype = BOOLRESULT

    SHHandleWMActivate = aygshell[84]
    SHHandleWMActivate.argtypes = [ HWND, WPARAM, LPARAM, 
    SHHandleWMActivate.restype = BOOLRESULT
