I came from IBM Mainframes to PC's in the dawn of time. My obsessive-compulsive computer hygiene can't tolerate seeing anything blemish my clearly arranged desktop, nevermind an executable file and unsightly shortcut-icons, I know how to use existing commands, menus and taskbars, thanks. How do I move the firefox.exe from my desktop back into the C: root program files folder? I have tried all the usual old-tricks but she won't launch after modifying paths etc. Please help.
