How to Purchase a Windows Product Key

A Windows Product Key is a unique key that comes with a purchase of Microsoft software. It can be used to help identify, install, and even potentially restore the software to your PC or Mac if you purchased a Microsoft product previously. Windows 10 uses a digital license that is tied to your Microsoft account.  It is no longer necessary to enter a product key when installing Windows 10.  You can still purchase a Windows 10 license from Microsoft.
