Using Windows, you can just right-click on a folder and select "Delete from Quick Load".
Quickload is also a folder on your hard drive like this:
"C:\Users\USERNAME\AppData\Local\Native Instruments\Kontakt 7\QuickLoad\"

Usually there are no folders there until you create them by dragging Library folders (or subfolders or just individual instruments) over there to Quickload.
I do not use the "Wallpaper Browser" (I call it that because that is what it is good for) and I only use Quickload.
One can set up their own categorized browser and potentially much better than the wallpaper browser.
