It's not apparent what you've shown or what you're trying to get rid of. You aren't showing the title bar of that Window. If you're trying to get rid of Wordpad, it's a part of Windows so you can't get rid of it.
You know I was going to reply to this with a paragraph about how crazy I find it that you can't comprehend my OP, but I'll skip that because I feel like it'd get me nowhere.
I'm trying to remove the entire half of the window I clearly outlined in red, not the "wordpad" application, which can by the way be removed by simply uninstalling it, albeit you saying that you can't get rid of it. My old search bar was simply the white part NOT indicated by the red square, the more section and the extra white space on the right showing a specific application is the part I am trying to get rid of. This only just appeared and so I'm trying to get rid of it as I see absolutely no need for it and it makes the search bar FAR too large.
