I'm not sure, it really depends in Microsoft's execution of the vision.
Over the years, if they really make Cortana useful and seamles pdates and systems maintenance the default due to the new "cloud" nature of Windows, they might see a similar adoption or switching pattern as SaaS solutions have seen in business.
At this point most traditional or slow businesses still using licensed software with local IT admins are being outcompeted by more agile competition using SaaS solutions.
Then again, what alternative do corporates have? They could stick to an older version of Windows, and become less competitive (assuming Microsoft pulls it off), or switch to Linux, which is doubtfl for most office workers (though our entire devshop uses now Linux ultrabooks).
i also suspect that they are slashing their cash cow (corporate users among them) for the vague promise to be like google and facebook (the promise of add dollars).
