Log:
[SMSS2]: Implement SmpCreateDynamicEnvironmentVariables such that all the SMSS-generated
variables are created. Compared to SMSS it has some bug fixes and also handles the
safe-mode options key. Next step is to handle boot/setup/execute keys and get autochk
running from SMSS2.
[SMSS]: No longer initialize the registry, let SMSS2 do that now.
