一、了解什么是Windows系统激活及激活时间

在开始学习如何查看Windows系统的激活时间之前，我们首先需要理解几个关键概念。Windows系统激活是指通过合法的授权方式让操作系统确认为正版，并获得全部功能的过程。一旦成功激活，用户便可以享受持续更新以及完整的服务支持。而“激活时间”则指的是您的Windows操作系统被正式激活的具体日期和时间。掌握这个信息对于管理许可证、监控软件使用情况或解决潜在的技术问题都非常有用。

步骤：

1. 打开命令提示符：点击“开始”按钮，在搜索框中输入cmd后按回车键。
2. 在打开的命令提示符窗口里输入以下命令并执行：slmgr /dli（注意空格）。
3. 等待几秒钟，屏幕上会显示关于您当前Windows版本的信息摘要。
4. 查找输出结果中的License Status字段，确保状态为“已许可”。
5. 继续向下浏览至Original Activation Date项，这里记录的就是最初激活该Windows副本的确切时间。

二、为什么要查看Windows系统激活时间？

了解自己计算机上安装的操作系统何时被激活有着多方面的好处。首先，它可以帮助你验证所使用的Windows是否为合法授权版本；其次，当遇到任何与许可证相关的问题时，知道准确的激活日期有助于更有效地与微软客服沟通解决问题；最后，如果你是从二手市场购买了预装有Windows系统的电脑，则检查其激活历史也是必要的步骤之一，以避免将来可能遇到的法律风险。

步骤：

1. 如果你是企业IT管理员，定期检查员工机器上的激活状态和日期是良好实践的一部分。
2. 对于个人用户来说，在重装系统前后对比激活时间点，能够帮助确认新安装的系统是否已经正确地完成了激活过程。
3. 当怀疑自己的系统可能被盗版软件替换时，查看原始激活日期也是一种有效的自查手段。
4. 记录下每次更换硬件后的激活时间变化，对于追踪设备维护历史同样很有价值。
5. 保存好包含激活时间在内的所有重要信息截图或文本记录，便于日后参考。

三、除了命令行还有哪些方法可以查看激活时间？

虽然使用命令提示符查询是最直接有效的方式之一，但对于不熟悉命令操作的朋友而言可能会感到有些复杂。实际上，还存在其他几种相对简便的方法来获取同样的信息：

步骤：

1. 通过PowerShell：打开PowerShell控制台（可通过在开始菜单搜索框内键入powershell找到），然后运行命令`Get-WmiObject -Query "SELECT * FROM SoftwareLicensingService" | Select-Object OA3xOriginalProductKey, LicenseStatus,

1看起来在生成PowerShell命令时发生了了一个错误，导致命令变得异常冗长且无法使用。正确的PowerShell命令应该更加简洁。以下是简化后的PowerShell方法，用于查询Windows系统激活信息：
2
3### 步骤：
41. **打开PowerShell**：在开始菜单搜索框内键入`powershell`，右键选择以管理员身份运行。
52. **运行命令**：在PowerShell窗口中输入如下命令并按回车键执行：
6   ```powershell
7   (Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform").OA3xOriginalProductKey
8   (Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform").OriginalActivationDate

1. 查看结果：第一条命令将显示产品的原始密钥（如果有的话），第二条命令将显示Windows首次激活的日期和时间。

请注意，这些命令依赖于注册表中的特定键值存在，某些情况下这些信息可能不可用或已被删除。如果您没有看到预期的结果，请尝试使用前文提到的slmgr /dli命令，这通常是一个更为可靠的方法来获取激活信息。

此外，还有一些第三方工具声称可以提供类似的信息，但在使用这类软件时要格外小心，确保它们来自可信源，以避免安全风险。始终建议使用官方提供的方法来检查您的Windows激活状态。
