I downloaded and installed the litestep shell, and then I went to change the style and when I did nothing now shows up on my account except the wallpaper. I delted litestep but I still do not have a taskbar, icons, or acess to anything. I would like to reset my default shell, but I have no clue how to.

u have delated litestep? bad, you have to uninstall it if you don't like it. the easiest way is, that you install it again and do the uninstall, or you work through your Registry.

you have to change ONLY the shell value to explorer.exe nothing more if you dont install again)
