I have internet exp.10 on my windows 8 computer.
I'm trying to acess a web site of an older version.
It says some stuff about shcm and internet exp. 5
A guy at work had same problem and explained
How to acess these older browsers. I'm lost here.
How do I get this web page too convert to my
System

You don't convert that site to work with your browser... you make your browser act like its an older version. You do this via Compatibility view.
