如何以编程方式确定Windows PE版本？

import winreg

def get_windows_pe_version():
    try:
        # 打开注册表
        reg = winreg.ConnectRegistry(None, winreg.HKEY_LOCAL_MACHINE)
        
        # 打开Windows PE注册表项
        key = winreg.OpenKey(reg, r"SOFTWARE\Microsoft\Windows NT\CurrentVersion")
        
        # 读取Windows PE版本信息
        version = winreg.QueryValueEx(key, "ProductName")[0]
        
        # 关闭注册表
        winreg.CloseKey(key)
        winreg.CloseKey(reg)
        
        return version
    except Exception as e:
        print("Error: ", e)
        return None

# 调用函数获取Windows PE版本
pe_version = get_windows_pe_version()
print("Windows PE版本：", pe_version)
