If you use a product key to select a Windows edition, we recommend using the same key to activate Windows, so that the edition you are installing is the same as the edition that you select. The edition of Windows that you are installing must match the product key used to activate Windows.

The product key in the product ID file is only used to install Windows. You can reuse the product key in the file product ID for multiple installations of the same version of the operating system. When you change the operating system, product ID remains the same and not need to change. The product key is a 25 character alphanumeric code shown in five groups of five characters each (for example, BCDFG-12345-HJKLM-67890-NPQRS). Product ID is built into the hardware of the machine components. you try to upgrade to Windows 8.1 with the same product key? are you referring to the product key or Product ID?Ģ. Thanks for posting the request in Microsoft Community Forums.ġ. I would like to know if the change in the operating system will also change the product ID.
