I have legit access to an office 2010 kms host key. AFAIK, this key needs at least 5 unique clients to attempt activation against the host before any client can get activated. I also read somewhere, the kms host checks the CMID to determine whether the client is unique. Now, problem is I don't have 5 machines, at best I have 3. Qn. 1- How can I change CMID so the host will think its a different machine activating when actually it isn't? Is it even possible? Qn. 2- What determines CMID? Will reinstalling office or, say, reinstalling windows change the office kms CMID?
