That is not the case for:

Closing of stdin / stdout / stderr is task for external process (like CRON)
even on UNIX.

With simple:

  #include <stdio.h>
  #include <unistd.h>

  int main(int argc, char **argv) {


      return 0;

in Task Scheduler I see console window and supporting conhost.exe process.

OK. I know about run.exe from package:

  sdesc: "Launch cmdline programs with hidden console"
  ldesc: "Launch cmdline programs with hidden console"
  category: Base
  requires: cygwin
  version: 1.3.4-2

I tried:

  $ cp /bin/run.exe ~/usr/bin/runbash.exe

and provide path to ~/usr/bin/runbash.exe in Task Scheduler. Console window
still flashes.

With my tiny test utility:

  $ cp /bin/run.exe ~/usr/bin/runxtest.exe

it flashes too from Task Scheduler but for a moment not 10 sec ))

Same if I run by Win+R:

  $ run xtest

My goal to avoid any splashes on screen and possible keyboard focus stealing
from sudden task execution.
