I had the same issue, where we load balance our site across multiple servers, and I try to hit each one individually. What worked for me is going into your Internet Options, and on the Security tab, just remove the checkmark next to "Enable Protected Mode (requires restarting Internet Explorer)" and it should start using your hosts file entries.

See https://blogs.msdn.microsoft.com/fiddler/2011/12/10/revisiting-fiddler-and-win8-immersive-applications/ for a simple utility that allows you to disable the restriction so that you can load content from the localhost.

See https://blogs.msdn.microsoft.com/ieinternals/2012/03/23/understanding-enhanced-protected-mode/ for the gory details of the restriction introduced in Windows 8.

Also with Windows 8.1, unchecking "Automatically detect settings" at the LAN settings (connection tab) will enable custom entries in the HOSTS file.
