When I type www.localhost, where is index.html

I keep saying that when I type in www.localhost or local host or even 127.0.0.1, I DO GET A WEB PAGE. I want to know where this html file exsists on my compuuter so I can edit it and use it for website development. Is this not clear to anyone?

It is, but listen to the advice given by MilesAhead please. In addition I asked you twice to tell us what the webpage says.
Simply telling us "I get a webpage" is useless information for us, for all we know it could simply be a default 404 error page. Which would then mean there's no running webserver at localhost.

...the relevant FAQ in the link...

If this is the link: FAQ - Httpd Wiki
I can't find a relevant link either by searching it for "localhost".

Using Apache HTTP Server on Microsoft Windows - Apache HTTP Server
If you did in fact see the Apache placeholder page then:
I am going to read the manual for you, I'm also trying to hold your hand but I think I can't reach :)
The default path is C:\Program Files\Apache Software Foundation under which a directory called Apache2.2 will be created by default.
Hmmm, I would start looking there.
if you already have a file called htdocs\index.html <------ is this it?!?!?!
I hope I have the correct version...

Your school education is lost on you here. I was writing computer programs probably before you where born giblets.
I do know what a html file looks like. I also know that I do not have to install it in the default directory and that the directory would not be called Apache2.2 if this was not the version of Apache I installed.

I do know what I am doing. Need a professiona to help.

I installed apache_2.0.63-win32-x86-no_ssl.msi to

E:\Apache Group\

When I type http://localhost/ into any browser (Some here want to know what browser I am using for some strange reason)
I get a page that has two words

It Works.

If I type in http://localhost/index.html

I Get the same.
There is a folder with lots of html pages in difrent languages in

E:\Apachie Group\Apachie2\htdocs like
index.html.de, index.html.en, index.html.dk
BUT NO index.html

I Havw also
C:\windows\system32\drivers\etc\httpd.conf with
<Directory "E:/Apache Group/Apache2/htdocs">

ServerRoot "E:/Apache Group/Apache2"
DocumentRoot "E:/Apache Group/Apache2/htdocs" // No index.html herer
<Directory "E:/Apache Group/Apache2/htdocs"> // No index.html herer
UserDir "My Documents/My Website" // No such folder My Website

Being a website developer this might be an obvious question.
Have you created an index page or are you expecting one already exists ?

"It works" is what the Apache placeholder page says.
