Step 2: Check the email received after purchasing Windows 10

If you bought Windows 10 digitally from the Microsoft Store, you should have received an email with the product key. Check your email’s inbox, spam folder, or deleted items folder to find the email.

If you have signed in with your Microsoft account while using Windows 10, the product key will be linked to your account. You can log in to your Microsoft account on Microsoft’s website and navigate to the “Devices” section to find the product key.

Step 4: Check the confirmation email for OEM and retail purchases

If you purchased Windows 10 from a retail or OEM store, you should have received a confirmation email with the product key. Search your email for the email containing the product key.
