Every version of Windows that is created requires a product key for activation. The reason for this is to verify whether you are running a genuine, paid-for copy of the program. Those programs that aren’t quite so genuine are ones that don’t get the full benefits of the Windows programs and don’t work as well, either. Each Windows program is single licensed, which means that it can only be used on one computer at a time, and you will need multiple product keys to use Windows on more than one computer.
How To Find Your Product Key
For many years, Windows PCs came with product key stickers attached that you would then type in to activate your Windows program. However, as we move with the times, manufacturers are storing the licenses within the machine, and the information is automatically implemented when you install the operating system. This makes for a far better, far easier approach to using Windows 10 product keys.
If you have a newer Windows PC, you can log in and know your digital license has already been activated – particularly if you already have a Microsoft account. If you do have a digital license, you will see a warning saying “Windows is activated with a digital license.” If you are unsure, then speak to Microsoft who can verify this for you.
Currently, you can link a Microsoft online account to a Windows 10 license by clicking “add a Microsoft Account” on the bottom of the page, while providing your usual login information.
Changing Your Product Key
From time to time, you may have to change the product key. It’s unusual that you wouldn’t be provided with a product key upon purchase or installation, but if it does happen, you can use a generic temporary key to upgrade and keep you using the Windows 10 program – but only for up to 90 days before you need to enter a proper product key to activate the operating system.
Entering Your Windows 10 Product Key
How do I enter the product key for Windows 10?
