How can I disable my yahoo browser and add internet explorer as my browser?

Just to be clear, you can't disable an internet browser. Internet Browsers are just programs that allow you to surf the web. What I think you're asking about is how you can get the Internet Explorer browser.
Just download it and install it as a normal program from here: http://windows.microsoft.com/en-us/inter...ownload-ie
If you meant to ask about how to make Internet Explorer your default browser, than it will just ask you to make it the default once you open it.
Good luck
