They can't "de-activate" installations, but of course they can (and will) block the key from being activated with MS.
Yeah, blocking further activations won't do anything against the activation backup. My point was to explain why online activation worked for SoLoR, and why it will not work for long.
No, u Need 25 Windows 8 Clients (Real or Virtual Images). Only if this Count is reached the Activation Procedure Begins.
Ah, if that's right. But having an initial copy of the virtual server KMS, this process can be repeated. That is two VMs = 50 activations .... is not it?
I think installing the Windows 8 client license files on Server Core so that it takes Windows 8 GVLKs (making it a "frankenbuild") could work. If it's only used to bump up the client count on the server it doesn't matter if it's got proper files installed.
