win7系统激活后，当前密钥没有明文保存，使用
1 | slmgr -dlv |
只能查看部份密钥，如果查看完整的密钥呢？以下提供了四种语言取得完整的win7/8密钥，最简单的为第一种!
win10/11的密钥在注册表的
计算机\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform
右侧的BackupProductKeyDefault值，就是win10完整的密钥！
所以相比来说，win10 win11的密钥取得要简单一些!
- vbs代码最简单，新建文本文件拷贝以下代码并保存为vbs，直接运行就可以获取win7当前使用的完整密钥!

win7 win8 win10 win11通用取密钥的vbs代码

c++代码
先从注册表项中(HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductId)读取ProductId的二进制值，再使用下面的函数就可以解密win7/8系统当前使用完整密钥，而不是部份密钥1
