Minor typo: thw -> the

Great post, really interesting stuff! By the way, is `explorere .` a typo? It does nothing for me on the Windows command line. Seems like it might be `explorer .`, reading this: http://www.howtogeek.com/howto/windows-vista/stupid-geek-tricks-open-an-explorer-window-from-the-command-prompts-current-directory/ I haven't changed anything about that because I'm not sure.
