Ok let's see, according to the documentation, in windows, processes receive commands as a single line string and do some parsing of their own. Exec's Command function builds the command string by combining all arguments together using CommandLineToArgvW, that despite being the most common quoting algorithm doesn't work for every application. Applications like msiexec.exe and cmd.exe use an incompatible unquoting algorithm, hence the extra mile. Heres a different example using powershell

package main

import (
        "os/exec"
        "fmt"
        "log"
        )
func main() {
     out, err := exec.Command("powershell","remove-item","aaa.txt").Output()
     if err != nil {
         log.Fatal(err)
     } else {
         fmt.Printf("%s",out)
     }
