Why is my Microsoft Word asking for a product key?
This can happen if you don't uninstall the pre-installed version of Office on your new PC before installing a volume license version of Office. To stop the prompts for activation, make sure your Office uses volume licensing and then update the registry.
How do I know if my Office product key has been used?
You can go to www.office.com/setup to redeem. Them go to www.office.com/myaccount to check if it was already associated with a Microsoft Account.
What is the difference between KMS and MAK?
Key Management Service (KMS) allows organizations to activate systems within their own network. Multiple Activation Key (MAK) activates systems on a one-time basis, using Microsoft's hosted activation services.
