I tried one API for windows which is not doing exactly the same but it
just restrict the shutdown (i have a utility which is cancelling the
shutdown by asking user, You want shutdown or not ? yes/no like this)
, but it will restrict the restart too , so we can create the app
again using same API and ask it to check the command line parameter if
/restart then restart otherwise don't do any thing just cancel the
shutdown from shutdown button any utitly or from any other option.

But still anybody can shutdown by pulling the power cable from the PC
as said above.
