在运行我的程序时，我用pygame.display.set_icon(icon)配置的图标只显示在窗口中，在任务栏中，默认的python图标保持不变。
有办法改变吗？

i_icon = os.getcwd() + '\\images\\icon.png'
icon = pygame.image.load(i_icon)
pygame.display.set_icon(icon)
pygame.display.set_caption("Test program")
screenSize =(640,480)

screen = pygame.display.set_mode(screenSize,0,32)
pygame.display.set_caption('My Test Program')


while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            # sys.exit()
        if event.type == MOUSEBUTTONDOWN:
            check_click(about, event.pos)

screen.blit(background, (0,0))

pygame.display.update()
