What is KMSpico?
KMSpico (Key Management Service) is a Windows and Office activator that bypasses Microsoft’s official licensing system by emulating a KMS (Key Management Service) server on your local machine. This tricks Windows and Office into believing they are activated through a corporate network, granting full functionality without a genuine product key.
How Does KMSpico Work?
Microsoft’s KMS technology is typically used by businesses to activate multiple computers under a single license. KMSpico mimics this system, allowing individual users to activate their software without connecting to an actual corporate server.
Once activated, Windows and Office remain functional indefinitely, with automatic renewal every 180 days (just like a real KMS activation).
