Rajiv,
I kind of disagree on using CPU for couple of reasons.
Maybe you got me wrong - it's not that I use the CPU myself - I agree with what you say. Personally, I don't see much sense in installing an outdated revision of a patch. Why not get *all* available fixes, when I'm installing a patch anyway? If possible, I always install all missing patches.
I do understand the reasoning behind the CPU and why people use it, though - it's what fixes all security issues with the least possible amount of changes to the system.
Martin.
