I'd guess it applies the initial deal Microsoft had with IBM to write DOS, along with keeping the rights to the IP. A whole lot of luck was involved: being in the right time at the right place, IBM focusing more on hardware, etc.

I ran a business for a while, and I distinctly remember several key moments where I got super lucky. Eventually the business got big enough that less luck was required to make it on a daily basis.
