How do I get Classic Folder Icons Back?

I have tried this with digital scrapbooking supplies stored on a WD Passport EHD. It will not work! I have thousands of kits, each one in it's own folder, and I cannot see what's inside of the folder! If I moved them all to the computer's internal HD, it would work but I really don't want to do that move.

Thanks Divya, But I need the flat folder back.  I have already selected a photo for each folder in customize, but they are so hard to see.  I have thousands of pictures of beads for my ebay store, etsy store and website and those vertical photos do not show me a good view of the beads.  I must open each folder to find the actual flat photos to identify my beads.

I really need the flat square folders back with a flat square picture on top so I can see what I am doing.  I am thinking of returning my purchase and new laptops and calling the whole upgrade off.  I cannot work like this, the inability to quickly locate my merchandise visually in the folders is wasting hours of manual labor every day.  It is such a simple request, I even tried bringing the folder icons over from Windows XP and I selected the flat folder, but then was not able to customize it with a photo, so it did not work. 

If there is a quick fix, or some download I could use, to be able to customize my folders I would keep Windows 7, but it looks like there is no solution.  I have scoured the q&a pages for hours to find some other user who found an answer or quick fix, but to no avail. 

I am not the only person who works with large quantities of photos and now cannot figure out what is in each folder, because the vertical/half view of the cover photo is not easy to see and identify.  It is a strange view that sometimes only shows me a corner of a bead or two, which is not acceptable.

I purchased 2 laptops with Windows 7 and spent over $2200 in local Staples thinking I would be making things faster/easier for my growing business.  Things have come to a halt, due to the photo folders being unrecognizable.  It is my inventory photos I need quick access to, to keep my business going and with one simple upgrade I seem to have destroyed my ability to work quickly and efficiently. 

I will go back to my old laptop and Windows XP if there is no fix and return my purchases to Staples with a hard lesson learned.  We have spent a week transferring everything to new computers, only to find we cannot work.  What used to be a simple 3 second process finding my beads in my folders, is now a nightmare of needless, time consuming searching...
