Answer 1

On Windows checking the result of os.FindProcess() seems to be enough to check if process is running.

func isProcessRunning(pid int) bool {
    _, err = os.FindProcess(pid)
    if err != nil {
        return false
    }
    if runtime.GOOS == "windows" {
        return true
    }
    return false // further checking for other systems then Windows is not supported here
}
