Well, the classic BSODs were not all Microsoft's fault, many of them were on 3rd party driver developers.

I think the worse thing here is all the subtle breakages and inconsistencies in Windows, as well as in the MS Office suite of products, constant redesigns of things that worked, adding layers upon layers of "make-up" on top that obscures functionality, etc etc.

Microsoft in the 90s was doing things that hadn't been done before with Windows. And the NT line, converging to consumers at XP, solved many of them, and by now they don't have an excuse any more.
