This is a built-in macro script within the toolkit. It automatically deletes any existing trial keys, clears conflicted licensing certificates, installs a generic Volume License Key (VLK), and forces the local KMS emulation to complete the activation script in a single click.

: Because KMS activations expire every 180 days, the toolkit installs a background system service that continuously resets the activation clock. The Severe Risks of Using Unauthorized Activators

The toolkit bypasses standard licensing by creating a local instance of a KMS server on your machine.
