If I were CEO, I'd notice that smart phones, tables, Chromebooks, and a more successful Apple have shifted the market. Windows is only 10% of revenue, so I'm not about to throw it away, but it's declining, and it's my focus. I'd let the engineers do the big breaking change that they've been clamoring for and make sure a key goal is cost savings from dropping legacy platforms. This sets up Windows to go into maintenance mode in 2035.
