This key is used during the installation of the development environment (Platform Builder).
There are two primary ways keys are handled in the embedded world:
SYSGEN_ETK_SYS_RETAIL_LICENSE_ARM (Note: These were built into the Platform Builder demo images. They are not 25-character strings but boolean build flags.)
You cannot simply type a 25-character alphanumeric code into a WEC7 device as you would on a desktop PC. The "key" is either pre-programmed into the device’s hive-based registry or it doesn't exist.
