programmatically reboot in safe mode then execute program

Question

I have a program and once the is button clicked I want a message to appear that will tell user that the computer is rebooting (with ok/cancel option), then the computer will reboot. Yet the kicker is, I want it to reboot into safe mode. Then when the user is logged into safe mode, it will automatically start a program on startup.

Now I realize that this is possible by programmatically editing boot.ini with /safemode, task to start program once computer logs in,then telling the computer to reboot.However, the end user is assumed to have not enough knowledge of Windows to reverse these settings manually.

What I want is, after the end user is done with the program in Windows Safe Mode, they can simply reboot the computer and resume using Windows with out manually changing any settings to the way they were before booting into safe mode.

NOTE* the program that will run in safe mode, has been tested to work in safe mode. I just need to know how to get the end user to safe mode and run the program automatically with out the end user having any knowledge of how to reverse these settings.

Could anyone suggest a method to execute all this madness? An example in C# or vb.net would be great!

Thank you in advance!
