I've read a lot, but probably not all of the 13,155+ posts on the subject and still have a few questions regarding the various KMS emulator tools which are available. 1. Are they built with a real, leaked KMS key, or is there some sort of anonymity or randomness? The reason I have this concern is because MS are actively scanning port 1688 for rogue KMS servers and when they find one, can determine the key it was installed with. I know someone who got an official email from MS anti-piracy informing that their KMS had been blocked because they discovered it to be available online. 2. Which of the tools is most suitable to replace an existing legit KMS server, for the same reason as stated above, not wanting anyone to be able to analyze it to determine whose key was used to build it? It seems most of the tools are suited for localhost installation but might be adaptable for network use. Ability to activate localhost isn't required if the host is already activated by another method. 3. Assuming nobody wants to give a direct answer to the above, can you point me to where it's listed the features and limitations of the various tools?
