I've installed English Windows 8 x64 on my notebook and selected Slovenian as locale during installation. Like so:
The problem I'm having now is that my tiles on start screen display in Slovenian even though my installation is English. I've also edited languages, adding English (British) on the list and putting it on top of Slovenian, but tiles still use Slovenian.
All previous Windows versions were able to have English UI with a particular locale for input, time, dates, currency etc.

To resolve your language conflict, add a new language
Open the English language catalogue:
Pick whatever English language you prefer and Add it:

Pick the Slovenian keyboard layout, add it and save your setup:
You can now Move up your new configuration and Remove the old one.
Your date, number and time formats should still be set to Slovenian:
Restart Windows.
