We are using Windows 7, so there's that, then the steps move about depending on the web site.
So while one can write in generalities you want the actual directions. This isn't possible since the steps vary with the site and then we have to know the drive letter of the USB drive and so on.
This is where most folk complain as there is no one way to get this done.
I am trying to download some free "backgrounds", to add to my home computer. So far, though, I have found NO sites, which give actual "directions", especially if I want to download the image to a flash-drive, to use on another computer.
In fact, I find no directions, of any kind.
In simple, basic, conversational, English (NO computer code, please), would someone explain HOW I can download "backgrounds", to a flash-drive, so that I may install in my home computer?
