In an embodiment, environmental functionality of the system software may be changed by altering guarded system data which may affect behavior of the system software. A user may provide state change information for altering a state of the system software, which may thereby alter the environmental functionality of the system software. In some implementations, the state change information may include a product key or any alternative activation/identification datum. The guarded system data may be altered based on the state change information. Upon startup or after detecting altered guarded system data, the system software may set configuration parameters, based on the altered guarded system data or a detected hardware configuration, to enable a particular environmental functionality of the system software.
