If you use CreateProcess() directly instead of relying on system() you
can specify that the process be created detached (dwCreationFlags
contains DETACHED_PROCESS) without a console.  But CreateProcess() is a
lower level API than system(), so you potentially have to replicate a
great deal more logic, notably the fact that system() runs the command
through the shell (i.e. %COMSPEC% /c command) and that it handles
quoting.  CreateProcess() does none of this, you must handle it all
yourself.  But for a fixed command this is usually not a problem, and in
fact you gain a small bit of efficiency if a shell is not required, e.g.
there's no redirection.
