KMSpico is a tool that emulates a local KMS (Key Management Service) server to activate Windows and Office without an official license key. Capable of activating Windows (7, 8, 10, 11) and Office (2010–365). Not an official Microsoft product; usage violates licensing and may be illegal. Downloads often flagged by antivirus and risk carrying malware. Many users caution against it—for example: “DO NOT USE KMSPico… it is primarily a trojan…” :contentReference[oaicite:4]{index=4}.
