如果您在尝试激活Windows时收到以下消息，则您键入的产品密钥无法用于激活此计算机上的Windows ；那么这篇文章将帮助您解决这个问题：

您键入的产品密钥不能用于激活 Windows

在我们开始之前，您首先需要确保您从真正的卖家或来源获得钥匙。如果密钥是由在线网站提供给您的，因为它的价格较低，那么您的密钥很可能已经过期，通常是MAK 或 KMS 密钥的情况。如果是这种情况，您需要获取Windows Keys，最好的地方是Microsoft Store。

如果您确定密钥是真实的，请遵循以下建议：

1]检查^(Check)您是否使用了正确的密钥

检查您的Windows^(Windows)的密钥 ( Retail/OEM /Volume/etc .) 。您可能输入错误，因此导致错误。

2]检查^(Check)密钥是否适用于该特定Windows版本

如果您已安装Windows 10 专业版^(Pro)，但使用的是Windows 10 主页^(Home)键，则它不起作用。但是，如果您在Windows 10家庭版上使用^(Home)Windows 10 专业版^(Pro)密钥，它将简单地升级，并且没有回头路。您必须卸载密钥，然后重试。

3]运行Windows激活^{(Run Windows Activation)}疑难解答

它在Windows 10 设置^(Settings)中可用。导航^(Navigate)到更新^(Update)和Security > Activation，然后查找疑难解答。点击^(Click)运行，等待结果。如果计算机在连接​​到Microsoft Server时出现问题，并且您的密钥很好，它应该会激活您的Windows副本。这篇文章可以帮助您进一步解决 Windows 激活状态的问题^{(troubleshoot the Windows Activation States)}。

4]密钥^(Key)可能已经在使用中

如果您想在另一台 PC 上使用相同的密钥，您必须先停用该计算机上的Windows 密钥^{(Windows Key)}。虽然我们有关于如何做到这一点的完整指南^{(complete guide on how)}，但您必须使用 slmgr.vbsMicrosoft 的命令行许可工具。

slmgr.vbs /dlv all
slmgr /upk <Activation ID>

但是，对于已经在使用的密钥，您应该会得到一个不同的错误，这应该清楚地表明该密钥是否正在使用。但是，如果您知道密钥已在使用中，则值得一试。

我希望这篇文章很容易理解，并且您能够使用Windows 10激活密钥解决问题。

The product key you typed cannot be used to activate Windows

If you receive the following message when you try to activate your Windows, the product key you typed cannоt be used to aсtivate Windows on this comрuter; then this poѕt will help you resolve this:

The product key you typed cannot be used to activate Windows

Before we start, the first thing you need to make sure that you got the keys from a genuine seller or source. If the key was given to you by an online site because it was priced less, then chances are your key has expired, usually the case with MAK or KMS keys. If that’s the case, you need to get Windows Keys, and the best place would be from the Microsoft Store.

If you are sure the keys are genuine, then follow these suggestions:

1] Check if you are using the correct key

Check the key (Retail/OEM /Volume/etc.) for your Windows. It is possible that you may have mistyped it, and hence it resulted in the error.

2] Check if the key is meant for that particular Windows edition

If you have installed Windows 10 Pro but are using Windows 10 Home keys, it will not work. However, if you use Windows 10 Pro key on Windows 10 Home, it will simply upgrade, and there is no going back. You will have to uninstall the key and then try again.

3] Run Windows Activation troubleshooter

It is available in Windows 10 Settings. Navigate to Update and Security > Activation, and look for the troubleshooter. Click to run, and wait for the results. If the computer has issues connecting to Microsoft Server, and your keys are fine, it should activate your Windows copy. This post may help you further troubleshoot the Windows Activation States.

4] It is possible that the Key is already in use

If you want to use the same key on another PC, you will have to deactivate the Windows Key on that machine first.  While we have a complete guide on how you can do that, you will have to use slmgr.vbs or Microsoft’s command-line licensing tool.

slmgr.vbs /dlv all
slmgr /upk <Activation ID>

However, you should get a different error for keys that are already in use, which clearly should tell if the key is in use. But it is worth a try if you know the key is already in use.

I hope the post was easy to follow, and you were able to resolve the issue with the Windows 10 activation keys.
