Here is the text for the process. This method does not "crack" Windows or generate a fake license. It uses a generic Volume License Key (GVLK) to bypass the initial entry screen, but it requires that your computer is connected to a KMS (Key Management Service) server (usually a corporate network) or that you are using a KMS emulator (which is considered software piracy).

Disclaimer: This guide is intended for educational purposes or for users who have a legitimate Volume License agreement with Microsoft. Activating Windows without a valid license violates Microsoft's Terms of Service. how to activate windows 10 without product key using cmd
