在如此多的Windows 激活错误代码中，我们已经看到0xC004E028，当您没有耐心或Windows激活仍在进行中时会发生这种情况。

Windows 激活错误代码 0xC004E028^{(Windows Activation Error Code 0xC004E028)}

所以你已经请求激活了，但是如果你尝试激活，那么你会看到这个错误。除非第一次激活失败，否则第二次激活不会完成。我说第二次激活的原因是您可能不小心使用了不正确的密钥，然后尝试更改它。

在激活过程中，Windows 将密钥发送到 Microsoft 服务器以对其进行验证。除非该过程返回结果，否则您无法再次激活Windows。

也就是说，如果您不尝试手动激活Windows，则可能是因为来自Server的延迟响应。有时^(Sometimes)验证需要很长时间，如果您再次尝试激活它，您将收到此错误代码 0xC004E028。我建议您等待，仅在 激活失败时才激活。

如果这不起作用，那么您可以尝试通过电话、Microsoft Chat 支持或电话支持^{(Microsoft Chat support or call support)}等方式激活 Windows。它们最终都以相同的方式工作，即由Microsoft 服务器^{(Microsoft Servers)}验证其有效性。

如果这发生在企业^(Enterprise)级，一些计算机需要连接到公司的服务器以进行验证检查。它们使用MAK 密钥激活，并且在重新安装时可能需要新密钥。

所以很明显这里不需要故障排除。您只需要等待看到成功激活或另一个错误。^(All)企业用户^(Enterprise)应与 IT 管理员联系以获得正确的解决方案。这些计算机应至少在六个月内连接到网络一次。

Fix Windows Activation Error Code 0xC004E028

Out of so many Windows Activation Error Code, we have seen, 0xC004E028, which happens when you are either out of patience or the Windows activation is still in the process.

Windows Activation Error Code 0xC004E028

So you have already requested the activation, but if you try to activate, then you will see this error. Unless the first activation has failed, the second activation will not complete. The reason I am saying the second activation is that you may have accidentally used an incorrect key, and then trying to change it.

During the activation process, Windows sends out the Key to Microsoft servers to validate it. Unless the process comes back with a result, you cannot activate Windows again.

That said, if you are not trying to activate Windows manually, then it can be because of a delayed response from the Server. Sometimes validation takes a long time, and if you try to activate it again, you will receive this error code 0xC004E028. I will suggest you wait and only activate if the activation fails.

If this doesn’t work, then you can try the method of Windows Activation over phone calls, Microsoft Chat support or call support, and so on. They all work in the same way at the end, i.e., validated by Microsoft Servers for validity.

If this is happening on an Enterprise level, some computers need to connect to companies’ servers for a validation check. They are activated using the MAK keys and may require a new key when they go through reinstallation.

So it is clear that there is no troubleshooting needed here. All you need is to wait to see either successful activation ore another error. Those with Enterprise should connect to the IT admin for correct resolution. These computers should connect to the network at least once in six months.
