WE8S 180 days evaluation key

Add 180 days evaluation key which applied from microsoft embedded web link to Windows Embedded 8 Standard ICE and add the features and drivers you need  then create a disk from configuration file. Boot the usb flash drive from system then start to build we8s. After finished installation, "the license is expired" pops out on windows desktop. The system will show "Security-SPP" error and reboot system every 10 ~ 30 minutes.
It seems applied 180 days evaluation key is no use. I replace the PID which applied by CLA no and rebuild the image. The S/N entry page pops out after sysprep. The license is expired message disappear.. Everything is normal.
