Stop 0xC000021a in Windows Session manager while starting windows


Consider the following scenario:
  • In Power Option control Panel->"Define power buttons and turn on password prection" window , you choose "shut down" in the Power button setting drop-down list.
  • Restart the computer. While system is booting up, press the power button to trigger shutdown

You may see the following error message on a blue screen: 



While the system kernel is handling the shutdown event trigger by the user, smss.exe is still attempting to launch wininit.exe


Microsoft has confirmed this to be a problem in Windows 7.

To completely avoid this symptom, please change the Power button policy to any other options than "shut down".
