I fixed the smiley problem for you in your first post. (There's a checkbox to disable smileys.) I'm unfamiliar with Vista, so I do not know what the best way to get rid of it would be. I would suggest just booting to Windows XP Pro and modifying the boot file. An easy and safe way to do that is to right-click My Computer, click Properties, click the Advanced tab, and click Startup and Recovery. The top section should be at least fairly self-explanatory with your level of understanding. If you need any more help let us know.
