KMSPico is a popular tool used for activating Microsoft products like Windows and Office without requiring a genuine license key. It works by emulating a Key Management Server (KMS) to bypass activation checks. People might want to download it for free to avoid purchasing an official license, though it’s important to note that using such tools can be illegal and might expose users to security risks, such as malware or viruses. Additionally, using cracked software often violates Microsoft’s terms of service.
