As far as I know the E14's operating system cannot be downgraded / clean win 7 install meaning that Sony has not published any drivers for Win 7 for that specific machine. If you have one with the touchscreen... it's very likely that you'll lose any touchscreen functionality.

As confirmed by Sony's support page : http://www.sony.co.uk/support/en/product/SVE1512C5E/tips-and-solutions
