If you're using Windows 8 and don't see a Start button, move your mouse cursor to the bottom-left corner of the screen and click the "Start" pop-up that appears. This will search for Internet Explorer, and should show it as the first result. Internet Explorer comes installed on all versions of Windows and can't be removed, so you should always be able to find it by searching this way. This will start the web browser. Right-click the "Internet Explorer" icon that appears in your taskbar at the bottom of the screen and select "Pin to taskbar." This will keep the Internet Explorer icon in your Windows taskbar even when it's closed so that you can quickly open it. If Internet Explorer does not open, or closes immediately after opening, try the following:  Open the Control Panel from the Start menu. In Windows 8.1 and 10, right-click the Start button and select "Control Panel." Click "Network and Internet" and then "Internet Options." Click the "Advanced" tab and then click "Reset..." Check the "Delete personal settings" box and then click "Reset." Reboot your computer and then try launching Internet Explorer again.
