Microsoft didn’t come up with that. The bean-counters at Microsoft should offer daily thanks to the Gods for the rise of Compaq and the other early IBM-compatible clones.
In sequential order:
• IBM prototypes a personal computer, to be called the Personal Computer, or PC
• IBM has the most expensive brainfart in history and decides to farm out the OS development to any 3rd party who wants to supply them with one
• Microsoft beats out CP/M for the bid, handing in something they acquired, originally called QDOS (quick and dirty operating system), repackaged as MS-DOS
• The IBM-PC does quite well, marketshare-wise. Each IBM-PC runs MS-DOS and ships with MS-DOS on diskettes (or, upon the ubiquity of hard drives, preinstalled)
• Other hardware companies reverse-engineer the IBM-PC and produce IBM-compatibles. They run MS-DOS, too.
• MS, which didn’t do anything in particular to make that happen, sure doesn’t do anything to prevent it. IBM does, (tries to change architectures, micro-channel I think it was called? Also tries to supplant MS-DOS with OS/2), but to no avail. So no one needs an IBM-PC to run MS-DOS (and later, Windows).
• Fast forward a couple decades and Apple, whose computers were not reverse-engineered and whose OS is produced in-house to run only on their hardware, is still in business and doing decently well; Microsoft, whose OS runs on everyone’s hardware (including Apple’s nowadays), kicked everyone’s butt and is the biggest software company on earth; IBM, whose hardware got reverse-engineered and the OS of which is made by other people, bailed out of the personal computer business (they put their logo on machines made by another company).

But Gates had the foresight to retain rights to the OS. IBM didn’t think that was abig deal because they didn’t foresee the clone wars. I think there may have been a legal reason as well. IBM had been forced to unbundle their SW from their HW for their mainframes, so this may have been an easy way to do that. And after all, the money is in the HW, right?
