i tend to leave programs like that alone i had a bad experience with a similar program and had to reinstall windows tweaks to your pc can be done by yourself just do some googling or post on hear for solid advice
i use system mechanic 6 and it works well. it keeps my pc clean and clutter free, it maintains my registry, and all the little tweaks (like removing the shortcut arrows) without any problems. i've been using that program since v3.7 without a hitch.
