I sometimes do not understand why Microsoft only does these things for the USA and UK. Students in the UK and US with a valid email address (an email address given by the college or university, e.g. name@leeds.ac.uk) will be able to purchase Windows 7 Home Premium or Windows 7 Professional (upgrade versions) for #30 and $30 respectively.
The offer will run until 3 January 2010 when the prices will revert to normal.
