How do I get rid of that IE8 button?

I do not want IE8; I tried it and my computer crashed. I do not want the button for it. It's waste of space on my toolbar. How do I get rid of it?|||There is no need to get IE8 to remove the button. All you need to do is uninstall your Y! toolbar and get a later version at toolbar.yahoo.com.|||Try removing the application is windows ..uninstall using control panel/ remove programs ...or you can right click the task bar and go to properties/ notification area/ customize/ and select the program (in your case IE) and select hide from pull down.
