Windows 10的每个许可副本都有一个唯一的许可证密钥，如果您需要重新安装Windows，您可能需要找到Windows 10产品密钥才能重新启动和运行。
问题是大多数人甚至从未见过他们的密钥，因为他们购买了预装Windows的计算机。(Windows)你也可能丢失了你的或忘记了你用它做了什么。好消息是，有许多不同的方法可以确定您的许可证密钥。
此外，请务必在我们的 YouTube 频道上查看我们的短视频，(short video on our YouTube channel)该视频将引导您了解我们在本文中所写的信息。
但首先，你应该知道的一些事情(But First, Some Things You Should Know)
您的Windows 10产品密钥未锁定到任何类型的特定Windows 10媒体。如果您丢失了使用Windows 10的光盘或闪存驱动器，您只需下载一个新副本( download a new copy)并从中安装即可。密钥只是您的许可证的代表。
您的 Windows 10 许可证也锁定到特定计算机的硬件。如果您对硬件进行了重大更改，或者完全更换了计算机，那么您必须重新激活(reactivation)，以便将您的许可证绑定到新的硬件配置。如果Microsoft认为您通过同时在多台计算机上安装Windows 10来滥用您的许可证，他们可能不愿意这样做。
你可能不需要它(You Might Not Need It)
如果您有Microsoft 帐户(Microsoft Account)并且之前已将其链接到您的 Windows 10 产品密钥，那么您在新安装时只需使用您的帐户详细信息登录即可。查看这篇文章(this article)，了解如何链接您的产品密钥以了解其工作原理。
当您从“本地帐户”切换到使用您的Microsoft 帐户登录(Microsoft Account)时，这可能会自动发生。如果您尝试激活Windows的副本，只需将您的帐户从本地更改为Microsoft，它应该可以工作。
如果您升级了Windows 7(Windows 7)或 8的副本，这同样适用，您需要一个Microsoft 帐户(Microsoft Account)。只需(Simply)使用您的帐户凭据登录Windows，因为此处也不涉及产品密钥。
检查您的零售箱(Check Your Retail Box)
这是非常明显的，我们知道。仍然应该提及的是，如果您购买了盒装零售Windows 10副本，这是查找Windows 10产品密钥的最简单方法。它应该在盒子里面印上什么东西。
直接从 Windows 获取(Get It Straight From Windows)
如果您有Windows的激活副本并且只想查看产品密钥是什么，您所要做的就是转到Settings > Update & Security > Activation，然后检查页面。如果您有产品密钥，它将显示在此处。如果您有数字许可证，它只会这么说。
检查您的计算机是否有贴纸(Check Your Computer for a Sticker)
如果您购买了预装Windows 10的计算机或笔记本电脑，请检查机箱是否有显示Windows 10产品密钥的贴纸。这在一体式超极本等高端笔记本电脑中变得越来越不常见，但许多电脑仍然在贴纸上显示其产品密钥。
检查 PC 随附的文件(Check The Documents That Came With Your PC)
如果看不到标签，则计算机随附的文档包中可能有真品证书。假设您没有扔掉所有这些小册子，您可能会很幸运并在防病毒软件包和外围设备的报价之间找到您的产品密钥。
使用第三方工具(Use a Third-Party Tool)
从正在运行的机器中检索产品密钥的最简单方法之一是使用第三方实用程序。Produkey在最新版本的Windows 10上为我们完美运行。只需(Just)运行该程序，您的产品密钥就在那里。
请注意，某些反恶意软件程序包(anti-malware packages)会将 Produkey 标记为“PUP”或潜在有害程序(potentially unwanted program)。它不是病毒或任何对您的系统有害的东西，PUP只是黑客可以用来破坏您的机器的工具(could )。但是，这是您的计算机，因此您(you )使用该工具检索您已经支付的密钥没有任何问题。
数字商店记录(Digital Store Records)
如果您通过Amazon或Microsoft Store等数字店面购买了Windows 10副本，他们将记录您的产品密钥。如果您删除了该电子邮件，它将在您收到的确认购买的电子邮件中或在您的订单历史记录中。因此，您所要做的就是搜索您的邮箱或登录您的在线帐户。
联系 OEM(Hit Up The OEM)
如果您购买了带有Windows(Windows)的预制计算机或笔记本电脑，那么您可能拥有OEM（原始设备制造商）Windows许可证。这使您的OEM有可能知道哪个产品密钥与您的计算机序列号对应。
无法保证他们会为您提供这些信息，但如果您在列表中排名靠后，那么这并不是最糟糕的选择。
最后的手段：致电微软(The Last Resort: Call Microsoft)
好吧，这可能不是最后的手段。虽然这些年来一直有起有落，但微软的在线客户服务在我们不得不处理的最后几次都相当不错。因此，如果您在激活Windows或查找Windows 10 产品密钥时遇到问题，很有可能与他们的一位服务代表进行实时聊天来解决问题。
你是钥匙大师吗？(Are You The Keymaster?)
随着微软(Microsoft)开始为其软件和服务转向基于云的订阅模式，Windows产品许可证密钥显然即将被淘汰。
然而，就目前而言，我们仍然不得不偶尔处理手头没有Windows(Windows)密钥的小障碍。最坏的情况是被迫购买全新的Windows许可证，但希望以上提示可以帮助您避免这种情况。
Find Your Windows 10 Product Key the Easy Way
Every licensed copy of Windows 10 has a unique license key and if you ever need to reinstall Windows, you’ll potentially need to find the Windows 10 product key to get things back up and running again.
The problem is that most people have never even seen their key, since they bought a computer with Windows preloaded. You may also have lost yours or forgot what you did with it. The good news is that there are many different ways to figure out what license key is yours.
Also, be sure to check out our short video on our YouTube channel that walks you through the info we have written about in this article.
But First, Some Things You Should Know
Your Windows 10 product key is not locked to any sort of specific Windows 10 media. If you’ve lost your disc or flash drive with Windows 10, you can simply download a new copy and install from that. The key is simply a representation of your license.
Your Windows 10 license is also locked to a particular computer’s hardware. If you make a big hardware change, or change computers entirely, then you’ll have to do a reactivation so bind your license to the new hardware configuration. If Microsoft thinks you are abusing your license by installing Windows 10 to multiple machines at the same time, they may be unwilling to do this.
You Might Not Need It
If you have a Microsoft Account and have previously linked it to your Windows 10 product key, all you have to do on a new install is log in with your account details. Check out this article on how to link your product key to see how it works.
When you switch from a “local account” to logging in with your Microsoft Account, this probably happened automatically. If you are trying to activate a copy of Windows, simply change your account from local to Microsoft and it should work.
The same applies if you upgraded a copy of Windows 7 or 8, for which you would have needed a Microsoft Account. Simply log into Windows with your account credentials, since there is no product key involved here either.
Check Your Retail Box
This is very obvious, we know. Still it should be mentioned since, if you bought a boxed retail Windows 10 copy, this is the simplest way to find the Windows 10 product key. It should be inside the box printed on something.
Get It Straight From Windows
If you’ve got an activated copy of Windows and just want to see what the product key is, all you have to do is go to Settings > Update & Security > Activation and then check the page. If you have a product key, it will be displayed here. If you have a digital license instead, it will simply say so.
Check Your Computer for a Sticker
If you bought a pre-built computer or laptop which came with Windows 10, check the chassis for a sticker which displays the Windows 10 product key. This is becoming less common with high-end laptops such as unibody ultrabooks, but plenty of computers still display their product keys on a sticker.
Check The Documents That Came With Your PC
If there’s no sticker in sight, there might be a certificate of authenticity in the document pack that came with your computer. Assuming that you didn’t throw all of those little pamphlets out, you might be lucky and find your product key in between the offers for antivirus packages and peripherals.
Use a Third-Party Tool
One of the easiest ways to retrieve your product key from a running machine is to use a third-party utility. Produkey worked perfectly for us on the latest version of Windows 10. Just run the program and your product key is right there.
Do note that some anti-malware packages will flag Produkey as a “PUP” or potentially unwanted program. It’s not a virus or anything harmful to your system, a PUP is just a tool that could be used by hackers to compromise your machine. However, this is your computer, so there’s nothing wrong with you using the tool to retrieve the key you already paid for.
Digital Store Records
If you bought your copy of Windows 10 through a digital storefront such as Amazon or the Microsoft Store, they’ll have a record of your product key. It will either be in the email you were sent confirming the purchase or in your order history, should you have deleted that email. So all you have to do is search your mailbox or log into your online account.
Hit Up The OEM
If you bought a pre-built computer or laptop that came with Windows, then you probably have an OEM (original equipment manufacturer) Windows license. This opens up the possibility that your OEM will know which product key goes with your computer’s serial number.
There’s no guarantee that they’ll have this information on hand for you, but if you’ve come this far down the list then it’s not the worst option.
The Last Resort: Call Microsoft
OK, this might not really be a last resort. While there have been ups and downs over the years, Microsoft’s online customer service was quite good the last few times we’ve had to deal with them. So if you do have problems activating Windows or finding your Windows 10 product key, there’s a good chance hopping on live chat with one of their service representatives will solve the issue.
Are You The Keymaster?
Product license keys are obviously on the way out when it comes to Windows, as Microsoft starts shifting to a cloud-based subscription model for its software and services.
For now however, we still have to occasionally deal with the minor road block of not having a Windows key in hand. The worst case scenario is being forced to buy a whole new Windows license, but hopefully the tips above will help you avoid that.
