If you are performing LTI deployment with MDT 2010 to install Windows on a target computer and you want Windows to automatically logoff once the installation has completed, you can do so by adding the following to the CustomSettings.ini file:
[Default]
SkipFinalSummary=YES
FinishAction=LOGOFF
If you do this, then as long as the task sequence successfully finishes, the target computer will skip the final summary wizard and automatically logoff when the task sequence finishes.
