How to find my Windows product key

If you are wondering how to find your Windows product key, the answer depends on how you got Windows. The 25-character key is usually on a label, a card in the box, or in a purchase email. Many PCs have no key at all, because they use a digital license instead.

Open Settings → System → Activation to check activation, then look for the key where you bought Windows.
A new PC usually has its key preinstalled or on a Certificate of Authenticity label, and a retail copy has it on a card in the box.
If you upgraded for free or bought the Pro upgrade in the Microsoft Store app, you have a digital license and no key to find.
