You just installed Windows Server 2012 on your brand new server and you open up Internet Explorer for the first (and last) time to download Google Chrome or Firefox...
Bam!
You get hit with this annoying message:

Luckily, it is really easy to turn off Internet Explorer's Enhanced Security Configuration so you can be on your way installing a better web browser. Simply open Server Manager, click on 'Local Server', scroll over and click 'On' next to IE Enhanced Security Configuration.

Check the Off button for the groups that you want IE ESC disabled for:

Now you can download another web browser without being bothered by annoying messages from Internet Explorer.
