从机器中提取 Windows 10 许可证密钥

Question

在整个办公室，我们有几台运行 Windows 10 的计算机（十几台），但我们不清楚我们的哪些许可证是在哪台计算机上激活的。是否可以从每台计算机中提取当前使用的许可证密钥？

我们不使用 AD 或 KMS 或类似的东西，每台计算机都是专门为处理它的个人设置的。我们知道我们拥有哪些密钥，但我们不知道哪些正在使用以及在哪里使用。我们混合使用 OEM、MSDN 和“常规”许可证。

Answer 1

您可以使用 NirSoft 的“ProduKey”。您可以在nirsoft.net上下载它。这是一个免费软件实用程序，它不仅可以让您查看 Windows 密钥，还可以查看各种其他 Microsoft 产品密钥。

此方法适用于批量许可证以及 OEM 和其他独立许可证。

请注意，它不正式支持 Windows 10，但到目前为止我的经验是成功的。

Answer 2

进入：

wmic path softwareLicensingService get OA3xOriginalProductKey 

进入命令提示符（管理员），然后按回车键。

这将显示每台机器的原始 Windows 10 产品密钥。

注意：这仅适用于 OEM 许可证。

Answer 3

如果您在连接到主板（OEM 密钥）的正版 Windows 副本上运行 Windows ，则可以在 Windows 管理员命令提示符下使用此命令：

wmic path softwareLicensingService get OA3xOriginalProductKey

或在管理员 Powershell 中

$(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

但是，如果您输入了产品密钥或将数字许可证连接到计算机，则此操作将不起作用。您可以使用 VBScript 获取计算机上的产品密钥，如此处所示，由Hackoo 编写。有许多不同的 VBScript 众所周知可以获取您的产品密钥，其中大多数都基于注册表，因为注册表以特定方式存储您的产品密钥（半加密，但如果您愿意的话，也不是真正的加密）。

有时，注册表值会更改或被删除，因此在这种情况下，如果这不是限制或问题，我会使用额外的第三方软件。我现在最喜欢的是ProduKey
