The frequency of activation renewal with a KMS Activator can vary. Typically, KMS activation is valid for 180 days, after which it requires reactivation. Some KMS Activators may automate this process, but manual reactivation is often needed periodically to maintain the activation status. It’s important to note that repeated use of such tools may pose risks and compliance issues, so using genuine software with proper licensing is highly recommended for long-term stability and legal adherence.
