The first time you upgrade to Windows 10 or do a fresh install on a new computer and activate your Windows 10, Microsoft will create a digital signature of your computer. This signature will lock your Windows 10 license to your hardware and will be used to activate Windows 10 automatically, the next time when you perform a clean install on the same PC.
However, if you want to change major hardware components (such as CPU or mainboard), or do a clean Windows 10 installation on a new PC, you have to reactivate your Windows 10 with a product key.
Some days ago, I wrote an article to guide you on how to find the Windows 10 product key on your computer. Read it to learn how to retrieve the Windows 10 product key from your existing Windows. After that, write it down somewhere so you can use it to activate your Windows 10 after performing a fresh install.
Besides, without knowing product key, you also can easily activate your Windows 10 after performing a clean install. But before having the ability to do so, you need to link your Microsoft account to Windows 10. Then, the next time you do a clean install, you only need to add your Microsoft.com account to Windows 10, and it will be activated automatically.
The best part is that you don’t need to remember your Windows 10 product key anymore. Instead, remember your Microsoft account and its password. That’s it!
How To Link Your Microsoft Account To Windows 10 Using Digital License
To get started, press Windows + I to open Windows 10 Settings.
Next, go to Update & security -> Activation.
There is an option to add a Microsoft.com account to Windows 10. Click on it to get started.
A new screen will pop up, which will ask you to provide your Microsoft account and its password.
After logging in, there will be a message that indicates your Windows 10 is activated with a digital license and now linked to your Microsoft.com account.
The next time you perform a clean Windows 10 installation on a different computer (or change your major hardware components), you just need to add this Microsoft account to your Windows 10 and it will automatically be reactivated.
Quite useful, right?
You no longer need to remember a long Windows 10 product key.
