J'ai downloader un fichier batch, info svp

Voilà le fichier batch, pensez-vous que c'est secure? Sinon pouvez-vous me dire quels parties ne le sont pas.
Le fichier sert supposément à arrêter certains services Windows afin que je puisses jouer en laggant moins. Je voudrais donc savoir quels services je devrais rester opérationnel au moins, dites-moi ce que vous pensez.
Merci
