Hi, Is it possible to abort computer shutdown from windows service?
A:
Yes. You can call shutdown /a using Process.Start
static void Main(string[] args)
{
Process p = new Process();
p.StartInfo.FileName = "shutdown";
p.StartInfo.Arguments = "/r";
p.Start();
Thread.Sleep(5000);
p.StartInfo.Arguments = "/a";
p.Start();
}
The above code tells the computer to shutdown and restart, waits 5 seconds, then aborts it.

`shutdown /a` only works for shutdowns that have a time-out period. If a user clicks Start >> Shut Down, `shutdown /a` won't abort it.

Will anything abort it? And even if it does, chances are half your processes have ended anyway, it's probably not a good idea to abort it at that stage.

AbortSystemShutdown
I've added a sample to my answer at the similar question here

This will not work for the same reason SLC's answer won't work - AbortSystemShutdown will only succeed when called "During the shutdown time-out period" [MSDN quote]. When a user initiates a shut down, there is no time-out period.
