DX10 was MS's opportunity to completely break the old DX models, which had been in existence since before the very concept of shader cores and about 90% of the other things that a graphics card has on it today. Windows Vista radically redefined the HAL, and was a good time to implement such a drastic change. Re-coding it to go back to the way XP interacted would hardly be a trivial undertaking and wasting that effort supporting a nearly 10 year old OS at that point simply because people didn't want to move would be a waste of resources.
You act like the move to Vista was a simple step from XP (Win7-Win8 is much, much more streamlined, and Vista-Win7 was as well - the HAL has not substantially changed) when in reality part of why it was such a bear was that it was truly a new design for MS from the ground up...they got a lot wrong, but the heart was in the right place, and Win7 was proof of that.
Forcing users to upgrade to win8 from win7 would require a product obsolescence that would put MS in the doghouse for a ridiculous timespan. It's true that many people will probably give this version a pass, but I'm tired of hearing people say "Look what they did with DX10 to try and sell Vista!" You're a programmer, you know better!!!!
FWIW, there are DX10 ports for XP out there in the wild but since M$ won't acknowledge that it actually does work on XP there are no drivers for DX10 in XP so it's pointless to bother with it.
