Speed of setup, and a standard stack everyone knows. You don't argue over which email server you use, you just setup Exchange. You don't argue over nginx, apache, etc just use IIS. It's also configured quite well out of the box, where as Linux you spend several days getting it all configured to perfection. When you just want to focus on the business problem at hand, I find it brilliant. Where as in other stacks you get caught up in technology, for technologies sake. I find you can go from 0 to release a lot faster.
