How to tell if it's MCE 2004

Microsoft Windows

Hi,

I've just bought the HP m370 in the UK. All the sales guff says it comes with MCE 2004, but if I open Control Panel .. System it shows as MCE 2002.

What's the quickest and simplest way to know the difference (for someone who's never seen MCE before buying the PC!!)
Are you asked for a _UK_ postal code when setting up the guide? Then it's
MCE 2004. MCE 2002 didn't know _any_ European postal codes.

Regards,«
