It uses whatever version you have configured, up to the version that is installed.
So if your computer has IE11 installed, then it can act as IE11 by making a registry change - detailed in the FAQ.
If you only have IE8 installed, then the latest version it can operate as with a registry change will be IE8.
If you’ve not made any registry change, the default is IE6 or IE7 depending on which of those you have installed.
