"Research"? What research?
Has Microsoft done any research on Windows 98, 2k, Millennium, etc.? Or, did they just crap out ever they want us to believe, much like they always do?
Granted, stuff security updates to the OS, itself could theoretically help protect an OS. However, if Microsoft wants to claim that some "research" proves this, they should actually do some.
On a brighter note, I'm glad to see that we (at my workplace) won't need to switch A/V programs for awhile. Most of our computers use XP, and some can't be upgraded to Vista, as they're quite old.
