If you are looking for the "story" behind these types of tools, here is the context:
: These unofficial tools create a "virtual" KMS server on your own computer. This tricks your operating system into thinking it has been authorized by a corporate network, thereby "activating" the software without a genuine retail key.
: KMSAuto Net is a popular "activator" based on Microsoft’s Key Management Service (KMS). KMS is a legitimate technology used by large organizations to activate many computers on a local network.
: Because these programs are unofficial and often distributed through unverified sites, they are frequently bundled with malware, miners, or spyware. Most antivirus software will flag them as "HackTool" or "Riskware."
