path_key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE,
                              r'SYSTEM\CurrentControlSet\Control\Session Manager\Environment', 0, winreg.KEY_ALL_ACCESS)
path_value = winreg.QueryValueEx(path_key, 'Path')
winreg.SetValueEx(path_key, "Path", 0, winreg.REG_EXPAND_SZ, '新的环境变量')
# 刷新注册表 更新环境变量 
HWND_BROADCAST = 0xFFFF 
WM_SETTINGCHANGE = 0x1A 
SMTO_ABORTIFHUNG = 0x0002 
result = ctypes.c_long() 
SendMessageTimeoutW = ctypes.windll.user32.SendMessageTimeoutW 
SendMessageTimeoutW(HWND_BROADCAST, WM_SETTINGCHANGE, 0, u'Environment', SMTO_ABORTIFHUNG, 5000, ctypes.byref(result))
