I believe you are referring to what used to be known as slipstreaming back in the days of Windows XP. Here is an article that works with USB to achieve the same for Windows 7

And if your already at Windows 7 Sp1 this other will assist for either ISO/DVD/USB installs.

There's a utility called rt7lite (the beta version), which allows you to integrate SP1 and other things into your installation DVD. It looks like the original site of that product is down, but it is still available at softpedia:

what i want to do is when i do a clean install i want SP1 to be installed also. I thought you were able to copy files in the upgrade folder then they would run. but i cant remember
I've requested that this question be deleted for the following reason:

The question has either no comments or not enough useful information to be called an "answer".
There's plenty of info here. Both rt7lite and slipstreaming works.
I must have missed it when you posted on Feb. 26

"what i want to do is when i do a clean install i want SP1 to be installed also"

The simplest way is to download the appropriate Win 7 SP1 (version the same as your existing installation) from here

burn as .iso to a DVD and use it for the clean install.  Your existing Product Key should work.
The first 3 comments are all good solutions.
Meanwhile even the original rt7lite site is back online:
