REPOST - Adding all drivers on new OS in 9020

Question

I'm re-posting this because the site has incorrectly labeled it SOLVED, it isn't.

Original post:

I recently bought a used 9020 which had win 10 installed. I prefer win 7 & have loaded that on a 2nd SSD. I have heard there's a "driver pack" I can run to automatically install all the drivers I need for this fresh install of win 7 SP1. Can anyone give me info on where to get & how to run this update pack?

Followup:

I have the pack 9020-WIN7-A13-MH44X.CAB, ran this before on another install, but I can't remember how to get the system to run the CAB & automatically load all the drivers. How is this done? I know it's a cab file, like a zip, and clicking in shows the files, but there are hundreds of them with no indication which is for this particular PC, and almost none are directly executable files. How do I get the system to run 9020-WIN7-A13-MH44X and automatically install the required drivers? If this is not the correct pack, which one is & how do I run it? Thanks!

Thanks redxps630. I ran Simplix (https://m.majorgeeks.com/files/details/simplix_updatepack.html) & I think it has updated the OS, the problem is getting all the drivers installed. That 9020-WIN7-A13-MH44X.CAB from Dell is supposed to do that (I THINK... ), but I can't figure out how to run it.
