KMSpico is a popular tool used to activate Microsoft products such as Windows and Office without requiring a genuine license key. It utilizes a Key Management Service (KMS) emulation method to bypass Microsoft’s activation process. People might use KMSpico to avoid purchasing expensive software licenses or to activate software on machines where traditional activation methods are not feasible. However, it’s important to note that using KMSpico can be illegal and may violate Microsoft’s terms of service. It also poses security risks, as downloading it from unreliable sources could expose your computer to malware.
