如何使用 CMD 或 powershell 查找许可证密钥而无需将 powershell 升级到 3.0 版本

如何使用 CMD 或 powershell 查找许可证密钥而无需将 powershell 升级到 3.0 版本

我遇到了一个问题,因为我正在尝试部署一个列出 PC 主要数据的脚本,但不幸的是我无法获取任何内容的许可证密钥。公司中的所有计算机(IT 部门除外)都使用 Windows 7 Pro 并具有 powershell v 2.0。我需要获取许可证密钥,但没有任何想法。我尝试进入 cmd,然后“wmic path softwarelicensingservice get OA3xOriginalProductKey”,但这不起作用。有什么建议吗?
