Thanks for the clarification. If you put the KMS key for Windows 7 into your host, but you don't have 25, will they eventually just cease to work like? I guess like if you never licensed them at all?

So if you had 4 Windows 2008 R2 licenses purchased as well as 10 Windows 7, that does not meet the 25 requirement. Does Office licenses count toward this? Also can 1 KMS host have all these licenses put into it to host out? I see all these guides show how to add one, but most will say if you add another it will erase the first one.
