KMS activation is an internal network activation solution designed by Microsoft for large enterprises or institutions. It allows companies to manage software licenses automatically through an internal KMS server, achieving permanent activation of devices. Although originally intended for enterprise intranets, technical methods have allowed public users to connect to open KMS servers for similar activation results. KMS activation has a 180-day validity period, with the system automatically attempting to renew every 7 days. As long as the device connects to the internet within the 180-day period, the activation status will remain valid, effectively achieving permanent activation. When using KMS activation, it is advisable to remain discreet and be aware of the legality and security of the sources.
