问题

超级用户读者user3486470想知道是否每个人都能在自己的计算机上看到Windows产品ID是一个值得关注的问题：

Is it a cause for concern that everyone can see the Windows Product ID on my computer? What is my Product Key given the Product ID shown on my computer?

用户3486470是否应该担心每个人都可以在其计算机上看到Windows产品ID？

答案

超级用户贡献者Mike和Raystafarian为我们提供了答案。首先，迈克：

Product IDs and Product Keys are two different things and they have nothing to do with each other. Product IDs are created upon Windows installation and are used for technical support purposes only. The Product ID has absolutely no similarity with the Product Key used for activation.

You cannot determine the Product Key if you know Product ID, and yes, it is safe for other people to see it.

接下来是Raystafarian的回答：

The simple answer is that these are two distinctly different things. This Microsoft KB article describes what is happening:

• A PID (Product ID) is created after a product is successfully installed. PIDs are used by Microsoft Customer Service to help identify the product when customers engage Microsoft for support. A Product Key is a unique combination of numbers and letters that is used during Microsoft software installation to unlock or open the product. If you do not enter the Product Key when you are prompted during the installation, the product may not open until you enter the product key.

Essentially, the Product ID can be tied to hardware, whereas a Product Key is tied to software. It is important to note that Product IDs are not only used for PCs with Windows installed on them but also for mobile devices, gaming c***oles, peripherals, etc.
