  3. 将上面的文本保存到桌面上带有“ .vbs”扩展名的文件中。
    温馨提示:为确保正确保存扩展名为“ .vbs”的文件,可以键入文件名并用双引号引起来,例如“ BackupWindowsKey.vbs”。
    如何在Windows 10,Windows 8和Windows 7中查看产品密钥
  4. 现在打开您的BackupWindowsKey.vbs文件
  5. 瞧,您的产品密钥会显示在屏幕上!
    如何在Windows 10,Windows 8和Windows 7中查看产品密钥

我在Windows 7,Windows 8和Windows 10上测试了该技巧。它在所有提到的操作系统中均能完美运行。
