go - How to hide command prompt window when using Exec in Golang?

Question

say i have the following code, using syscall to hide command line window

process := exec.Command(name, args...)
process.SysProcAttr = &syscall.SysProcAttr{HideWindow: true}
err := process.Start()
if err != nil {
    log.Print(err)
}

but when i compiled it and tried to run it in Windows, command line window showed up again

what can i do to prevent command line window from appearing?

PS i already know how to compile golang source into a Windows GUI executable using go build -ldflags -H=windowsgui, but doing so only ensures the program itself doesn't bring up a command line window, Exec will show those windows anyway
