Win 8.1 64 up to date

Windows Explorer opens to show a lot of stuff I don't want, mainly a list of folders which are also listed seperately under the Library heading. I only want to see my five hard drives listed. How can I do this please.

An ancilliary question re Libraries. All my 'library' folders are on other hard drives. I can add these to Windows' default library folders OK but application software frequently "sees" only the Windows library folder on C: Also Explorer gets confused by having additional library folders set up on other drives. How can I arrange things to either eliminate "libraries" altogether, or at least make them work properly with just the folders and drives I desire please?
