python
import ctypes
def check_miracast_support():
# Load necessary Windows libraries
user32 = ctypes.windll.user32
dwmapi = ctypes.windll.dwmapi
# Check if the computer supports Miracast
result = user32.GetSystemMetrics(0x8000) # SM_REMOTESESSION (0x8000) flag
if result == 0:
print("Miracast is supported on this computer.")
else:
print("Miracast is not supported on this computer.")
check_miracast_support()
