KMSAuto v1.6.2 is a version of an unauthorized activation tool (commonly called a “KMS activator”) used to activate Microsoft Windows and Office products without a valid license. These tools emulate a Key Management Service (KMS) server or install a KMS emulation locally so the target software believes it has been legitimately activated by a corporate KMS. “nesabamedia” in the string likely refers to a distribution source or repackager (sites or uploaders sometimes append their name to filenames or release notes).
