用python导出所有注册表项

以下是使用Python导出所有注册表项的示例代码：

import winreg

def export_reg_key(reg_path, file_path):
    try:
        key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, reg_path, 0, winreg.KEY_READ)
        winreg.SaveKey(key, file_path)
        winreg.CloseKey(key)
        print(f"Exported registry key '{reg_path}' to file '{file_path}'.")
    except Exception as e:
        print(f"Error exporting registry key '{reg_path}': {e}")

def export_all_reg_keys(root_path, output_dir):
    with winreg.ConnectRegistry(None, winreg.HKEY_CURRENT_USER) as root_key:
        for sub_key_name in winreg.QueryInfoKey(root_key)[0]:
            sub_key_path = f"{root_path}\\{sub_key_name}"
            file_path = f"{output_dir}\\{sub_key_name}.reg"
            export_reg_key(sub_key_path, file_path)

if __name__ == "__main__":
    export_all_reg_keys("Software", ".")

该代码将导出当前用户的所有注册表项到当前目录下的.reg文件中。您可以根据需要更改导出路径和根路径。
