Can you help me with my software licensing question?

The question is in the Title, I had the impression that you needed a Windows 2008 R2 KMS key to setup the KMS host, even if you wanted to activate Windows 7 licenses only. Am I wrong ?

Am I wrong ?

yes and no. You need a 2008 R2 KMS key to activate KMS, but what KMS can activate depends on the class of the key.

There is a KMS key that allows KMS to ONLY activate Windows 7 and no other WIndows Servers.

The KMs service activates anybody that asks for activation from vista on up. In order for your server to activate computers, you must have at least 5 Servers checked in for server activation to occur or 25 Windows 7 or Vista machines checked in for client activation to occur.
