Re: Better config in general
And still Windows let you install much more competitors' software than most other platforms.
It's not due to their generosity - far from it. To have a viable platform, you have to let anyone use it or it just wont become popular - it's not good enough to be an exclusive club. The trouble Microsoft have is they're both a provider and consumer of their platforms, and they need to sacrifice one part to benefit the other (I honestly believe splitting the company would benefit MS and everyone else).
There are also anti-competitive laws, but since MS platforms are quickly becoming irrelevant, I doubt these would apply for much longer.
