I bought a new laptop with Windows 7 and Chrome pre-installed -- no IE. Not in the Programs menu, the Desktop, etc., but I need it! So I downloaded it online, but it still didn't appear. I even tried uninstalling Chrome then installing IE, but Chrome re-appeared. So, where could IE be?
From your Start Menu, select Control Panel -> Programs and Features. On the left-hand side of the screen, you'll see a link for 'Turn Windows features on or off'. It will have a small shield next to it.
Click the link, and in the resulting dialog, make sure that Internet Explorer is check marked. If it's not, it won't be available to you.
