To activate Windows 10, you normally need a product key, but when you don’t have the product key with you, things might become a hassle for you. So, to give you the back and solve your problems of Windows 10 activation without a product key, we have compiled a list of methods that you can use to Activate Windows 10 for free.
With Windows 10, it is very easy to get the activation and reactivation. You can easily link your Microsoft account with Windows 10. So, if you have an MS account linked with the digital license key, you can use the same account to activate the Windows 10. Make sure your account is linked and then go to Settings > Update & Security > Activation, and then go to “Windows is activated with a digital license linked to your Microsoft Account” on the Activation field of the window.
