I don't understand what do you mean by changing files so you can see them.
Your screenshot show all your items are shown in icons. Do you mean you want to see the picture instead of the icon ?
If so, follow these simple steps......
click Start button > in the search box, type folder options > click Enter > click View at the top > UN-check the box " Always show icons, never thumbnails " > click OK when done.
If that is not what you are asking, please explain a bit further.
P.S. Just curious........
This is Windows 7 forum. If you just bought a new computer, shouldn't it be either Win 8 or Win 8.1 ? What version is it ?
