**UPDATE**
Some friends explained to me that on Vista you can uninstall spore just by going to Computer in the Start Menu and using the Uninstall or Change a Program button at the top of the window under where the toolbar is if you have it visible.
If this button is not there or it still does not work, DO NOT USE THIS VIDEO AS A LIST OF STEP-BY-STEP INSTRUCTIONS FOR MANUAL UNINSTALLATION! The actual help file is much more clear and to the point than my paraphrase was, so see here: http://tinyurl.com/spore-uninstall
It really peeves me off when people can't do the simplest tasks with a computer. I've read about technicians reporting that it's dark in the server room. Guess what the problem is? They didn't turn on the lights.
Every software program should have an uninstaller. If I don't want it on my hard drive, it shouldn't be this difficult to get rid of, especially considering that I got the uninstallation steps on an OFFICIAL TECH SUPPORT PAGE.
