Windows 11/10 提供了一个激活部分，您可以使用它来更改产品密钥。当您升级到下一版本的Windows或重新安装后重新激活时，它很有用。

但是，如果您尝试更改Windows产品许可证密钥，您会发现更改产品密钥链接不可用或不可见；您可能需要先检查您的Windows是否已激活，因为这通常发生在Windows尚未激活的情况下。如果不是这种情况，请按照前面的方法更改Windows 11/10产品密钥。

在Windows 11中，您会在此处看到此选项

在Windows 10中，您会在此处看到此选项：

更改^(Change)Windows 11/10中不可用的产品密钥链接

您可以使用SLUI命令或使用SLMGR 激活Windows 11/10/8/711/10/8/7^(SLMGR)。前者启动与单击“更改^(Change)产品密钥”链接时相同的界面，而后者则允许从命令提示符进行操作。如果您不记得产品密钥，并且您有旧安装，请了解如何找到该密钥。^{(find out how you can find the key.)}

1]软件许可用户界面^{(Software Licensing User Interface)}或SLUI

打开运行^(Run)提示 ( Win + R )，然后键入SLUI并按Enter键。它将启动“输入^(Enter)产品密钥”操作窗口。

现在在这里您可以输入Windows 密钥^{(Windows Key)}来激活窗口或升级。

2] SLMGR或软件许可管理工具^{(Software Licensing Management Tool)}

它是一个VBS文件，您可以从命令提示符^{(Command Prompt)}执行并使用Windows键来激活Windows。它是一个相当复杂的工具，在企业中用作批量^(Enterprise)激活管理工具^{(Activation Management Tool)}，用于多台计算机激活。

运行以下命令：

slmgr.vbs /ipk <Your Windows product key>

或者

slmgr.vbs [<ComputerName> [<User> <Password>]] [<Options>]

也就是说，如果密钥不起作用，请确保validate your Windows 11/10 product key.

我希望这篇文章能帮助您找到并更改产品密钥。

Change product key link not available in Windows 11/10

Windows 11/10 offers an activation section that you can use to change the product key. It is useful whеn you are upgradіng to the next versiоn of Windows or reаctivating after a reinstall.

However, if you try to change the Windows product license key, you find that the change product key link is not available or visible; you may want to check if your Windows is activated first because this usually happens if Windows has not been activated yet. If that’s not the case, then follow the method ahead to change Windows 11/10 product key.

In Windows 11, you see this option here

In Windows 10, you see this option here:

Change product key link not available in Windows 11/10

You can activate Windows 11/10/8/7 using the SLUI command or using the SLMGR. While the former launches the same interface as when clicking on the Change product key link, the latter allows it from the command prompt. If you do not remember the product key, and if you have the old installation, find out how you can find the key.

1] Software Licensing User Interface or SLUI

Open the Run prompt ( Win + R), and then type SLUI and press the Enter key. It will launch the “Enter a product key” action window.

Now here you can enter the Windows Key to activate window or upgrade.

2] SLMGR or Software Licensing Management Tool

It is a VBS file that you can execute from the Command Prompt and use the Windows key along with it to activate Windows. It is a fairly complex tool that is used as the Volume Activation Management Tool in Enterprise for multiple computer activation.

Run the following command:

slmgr.vbs /ipk <Your Windows product key>

Or

slmgr.vbs [<ComputerName> [<User> <Password>]] [<Options>]

That said if the keys don’t work, make sure to validate your Windows 11/10 product key.

I hope the post helped you find and change the product key.
