How do I disable the default player GUI? [Unanswered]

This is a more simple question.

I am just looking for a way to disable the default GUI of any player that joins my game. (Health, player list, Backpack, etc)

I have been looking around for a while now with no luck. I know it is probably right in front of my face, but I cannot seem to find it.

Just a quick explanation of how and where it is located would be great.

Thanks!

EDIT:

LocalScript that is placed into the player that connects:

check = true

repeat
game.StarterGui:SetCoreGuiEnabled("All", false)
if script.Parent.Parent == game.Players then
	check = false
end
until check == false

There's a method in StarterGui called SetCoreGuiEnabled. This hides and shows CoreGui elements like the health bar, player list, etc. You can find the wiki link here:
