Anyone interested in looking at an early version of Windows 10 can sign up to the ‘Windows Insider Program’ at preview.windows.com. Signing up is free, but you are encouraged to think of this software in terms of short term testing only.

The accompanying preview document (ed: no longer available) describes some important features of the upcoming O/S, including the new Start menu, window snapping and multiple desktops. Interestingly, it also steers clear of calling the next version ‘Windows 10’.
