What is Key Management Service (KMS) and how does it work?
KMS is a lightweight service that does not require a dedicated system and can easily be co-hosted on a system that provides other services. With KMS, you can complete activations on your local network, eliminating the need for individual computers to connect to Microsoft for product activation.A KMS host key is used only to activate the KMS host with a Microsoft activation server. A KMS host key can activate six KMS hosts with 10 activations per host. Each host can activate an unlimited number of computers. If you have an existing machine configured as Windows KMS* host, you will need to enter and activate the Office 2010 KMS host key before the KMS host can activate Office 2010, Project 2010, and Visio 2010. If you need additional KMS activations so you may activate more than 6 KMS hosts, find the telephone number for your Microsoft Activation Center to activate your KMS host.KMS requires a minimum number of either physical or virtual computers in a network environment.
