KMSPico is a popular software tool used to activate Microsoft products such as Windows and Office without a genuine license key. It emulates a Key Management Service (KMS) server, tricking the software into thinking it is properly licensed. Some users might want to download it for free to bypass the cost of official licenses, especially if they cannot afford them or are looking for a way to use the software without purchasing a license. However, using KMSPico is illegal and can pose security risks, including potential exposure to malware.
