Sorry H2SO4, but you are incorrect. True, they were cumulative for XP (although I'm not sure about SP3), but MS decided not to make SP2 for Vista cumulative (i.e. including SP1) in order to reduce its size (and hence the load on MS's servers).

The following is taken from Frequently Asked Questions: Windows Server 2008 Service Pack 2 and Windows Vista Service Pack 2 Notice the highlighted section regarding SP1 being a prerequisite for SP2.

Thank you Dwarf. I didn't know that. It must be the first non-cumulative OS SP since the NT days.
