For Windows 7 and older systems, the tool modifies the System Boot Code (Master Boot Record) and injects a SLIC (Software Licensing Description Table) into the system. This mimics the BIOS of major manufacturers (Dell, HP, Lenovo) to activate the OS permanently.

It uses KMS emulation, which mimics the server activation process that Microsoft uses for volume licensing.

The tool requires administrative privileges to modify registry settings and system files.
