Windows 10 967 Published by

Microsoft has published a new guide which explains how Windows 10 can be activated, following a slight confusion over who would have to enter a product key to activate their device



From Neowin:
The page confirms that users who upgraded from Windows 7 or 8.1, purchased Windows 10 or Windows 10 Pro upgrade from the Windows Store, or enrolled in the Insider program will have their copies of Windows 10 activated via "digital entitlement", which essentially means that you don't have to enter a product key.

Furthermore, Microsoft has also clarified that a product key is only required for users who buy a digital or physical copy of Windows 10 from an authorized retailer, have a Volume Licensing agreement for Windows 10, a MSDN subscription, or possess a device running Windows 10.
