用于读取注册表的Python代码

import winreg

def read_registry_key(key_path, key_name):
    try:
        # 打开注册表键
        key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, key_path)
        # 读取指定的值
        value, _ = winreg.QueryValueEx(key, key_name)
        # 关闭注册表键
        winreg.CloseKey(key)
        return value
    except FileNotFoundError:
        print(f"注册表键 {key_path} 不存在")
        return None
    except OSError as e:
        print(f"读取注册表键 {key_path} 失败: {e}")
        return None

if __name__ == "__main__":
    key_path = r"SOFTWARE\Microsoft\Windows\CurrentVersion"
    key_name = "ProgramFilesDir"
    value = read_registry_key(key_path, key_name)
    if value:
        print(f"{key_path}\\{key_name} 的值为: {value}")
