The European version still has a lot of IE integrated in the operating system. You would not gain anything buy going that route.
If you open Task manager you will find several Instances of Explorer running. Depending on what other Microsoft programs you have running at that time
Explorer, Iexplorer, Iexplorer32 etc.
Windows can not operate without it.
The European version just installs Whatever browser you choose as the default browser instead of IE.
