在今天的帖子中，我们将了解可能的原因以及您可以尝试解决的错误代码 0xc0ea000a（如果您最近更改了 PC 上的硬件，您可能会遇到Windows 10 激活错误）以及设备尝试自动重新激活并失败。

It looks like the hardware on this device has changed. Make sure you’re connected to the Internet and try again later (0xc0ea000a).

无法激活Windows 10 (0xc0ea000a)

大多数情况下，如果您在设备初始激活后更改了 PC 硬件（例如升级到新CPU或主板），则会遇到此 Windows 10 激活错误。^{(Motherboard)}但是这个错误也可以在系统崩溃后重新启动时触发。

但是，众所周知，此 Windows 10 激活错误通常会在几个小时后自行纠正。对此失误的解释是，有时Microsoft激活服务器可能会被激活请求淹没——因此服务器超载——这就是它说稍后再试^{(try again later)}的原因；如上图的错误提示。

因此，如果在出现激活问题后24-48 小时^{(24-48 hours)}后，您的设备仍未激活，您可以按照以下说明在硬件更改后手动重新激活 Windows 10^{(reactivate Windows 10 after a hardware change)}。

^{(Reactivate Windows 10)}更改硬件后重新激活 Windows 10

当您准备好重新激活时，请确保您的设备已连接到 Internet，然后按照数字许可证^{(digital license)}或产品密钥^{(product key)}的步骤操作。

如果您没有产品密钥或数字许可证，您可以在安装完成后购买Windows 10数字许可证。^{(Windows 10)}以下是如何进行购买：

启动设置^(Settings)应用程序。单击更新^{(Click Update)}和安全 > 激活 > 转到商店以打开Microsoft Store，您可以在其中购买Windows 10数字许可证。

• 如果您有数字许可证^{(digital license)}，请运行激活疑难解答。
• 如果您没有数字许可证，请输入您的产品密钥^{(product key)}，如下所示：

如果购买时您的设备上未预装Windows 10 ，并且您使用产品密钥升级到^{(Windows 10)}Windows 10，则在硬件更改后您将需要相同的产品密钥。 

要输入您的产品密钥，请启动“设置”^(Settings)应用。单击更新^{(Click Update)}和Security > Activation > Change Product Key。然后输入产品密钥。

如果您使用Windows 10产品密钥在您的设备上安装了Windows 10的零售副本，然后进行了硬件更改，请使用您的Windows 10产品密钥执行相同的过程。

如果此手动重新激活Windows 10设备的说明未能解决问题，并且24-48 小时^{(24-48 hours)}的等待时间已过，并且您的设备仍未重新激活，您可以联系Microsoft 支持^{(Microsoft Support)}。

Hope this helps!

Error 0xc0ea000a, Unable to activate Windows 10 after hardware change

In tоday’s post, we will have a look аt the possible cause and what you can try to resolve the error code 0xc0ea000a – which is a Windows 10 activation error that you might be faced with if you recently changed the hardware on your PC – and the device attempts automatic reactivation and fails.

It looks like the hardware on this device has changed. Make sure you’re connected to the Internet and try again later (0xc0ea000a).

Unable to activate Windows 10 (0xc0ea000a)

Most of the time you’ll encounter this Windows 10 activation error if you have changed your PC hardware such as upgraded to a new CPU or Motherboard – after the initial activation of the device. But this error can be triggered also on reboot after a system crash.

However, it is widely known that this Windows 10 activation error usually rectifies itself after a couple of hours. The explanation to this lapse is that sometimes Microsoft activation servers can be inundated with activation requests – hence the server is overloaded – which is why it says to try again later; as shown above on the error prompt.

So, if 24-48 hours have elapsed after the activation problem appeared, and your device is still not activated, you can proceed with the instructions below to manually reactivate Windows 10 after a hardware change.

Reactivate Windows 10 after a hardware change

When you’re ready to reactivate, make sure that your device is connected to the internet and then follow the steps for either a digital license or product key.

If you don’t have a product key or digital license, you can purchase a Windows 10 digital license after installation finishes. Here’s how to make a purchase:

Launch the Settings app. Click Update & Security > Activation > Go to Store to open the Microsoft Store where you can purchase a Windows 10 digital license.

• If you have a digital license, run the Activation troubleshooter.
• If you don’t have a digital license, enter your product key as shown below:

If Windows 10 wasn’t pre-installed on your device when purchased and you used a product key to upgrade to Windows 10, then you’ll need that same product key after the hardware change. 

To enter your product key, launch the Settings app. Click Update & Security > Activation > Change Product Key. Then enter the product key.

If you installed a retail copy of Windows 10 on your device using a Windows 10 product key and then made hardware changes, follow this same process using your Windows 10 product key.

If this instruction to manually reactivate your Windows 10 device fails to resolve the issue and also the wait time of 24-48 hours has elapsed and your device is still not reactivated, you can contact Microsoft Support.

Hope this helps!
