How to uninstall Internet Explorer from Windows
First, click on the Start Menu, go to the Control Panel and then click on the "Programs and Features" option.
When that window opens, click on the "Turn Windows features on or off" link. A new window will open up, showing a list of features that you can have on or not. Scroll down to Internet Explorer and uncheck it.
You'll see a notification asking whether you're sure, as this will affect other features and applications. Only do this if you're absolutely sure you want to get rid of Internet Explorer. If you are, then click okay.
You'll be prompted with a screen to restart your computer, and then you're done. Make sure you have another browser installed before you do this, so web pages open in a default program.
