According to the help for shutdown.exe, the /g switch does the following
/g Full shutdown and restart the computer. After the system is
rebooted, restart any registered applications.
I noticed that when I use this switch, not all the applications in use prior to the system shutdown are restarted.
So my question is this: is there a limit to the number of applications that can be restarted or is it that I don't understand the meaning of the term 'registered'? I suspect the latter to be case and would appreciate some guidance.
/g will restart any application that registered itself with the RegisterApplicationRestart API UNLESS the application was forcefully terminated. So, if you don't allow enough time /t for the application to gracefully save and close, it will not restart.
