I made consumer preview pe also. working on it. It gets to build winpe more easy. Services does not get much problems. Adding fbwf,ramdisk,winfsf services can turn full windows to a winpe (need stop some conlict services readyboost,peauth,hibernation.) As always main problem stays that
1-)System user doesn not have rights to run main programs (Explorer,Control Panel)
2-)Need change user to administartor.
My only main problem for now is to start windows firewall service. It is always pain. Without it wpeutil does not function as it should. Probably there is permission error at "mpssvc" and "sharedacess services". Because of that depended services not autostarts. Other services looks working. Bitlocker service makes crashes (disabled until i focus). Did not see metro apps anywhere. When user changed to administrator explorer gets some crashes. I put all system32 exe, dll's until i can optimize with wpeutil.
