Is anyone else having a problem with IE11?

First off, I'd get a different browser (I suggest Firefox) and see if that improves your browsing performance. If it doesn't, then it's not the browser that is the problem. Secondly, you're going to need another browser, as you need to remove IE11 before reinstalling the old one. (You need another browser to install IE9 after all)

The removal process is detailed below.

Save and close all Internet Explorer windows and then, run Windows Task Manager to end the running processes in background.

Press Windows 7 Start orb button and go to Control Panel.

Click Programs and choose the View installed updates instead.

Locate the following Windows Internet Explorer 11 or you can type "Internet Explorer" for a quick search. Then, you can directly press the Enter key on your keyboard.

Choose the Yes option from the following "Uninstall an update".

Please wait while Windows Internet Explorer 11 is being configured automatically.

Follow the Microsoft Windows wizard to restart your system.
