Baldrick's cunning plan?
The Windows OS is becoming ever more bloated, cumbersome, and difficult to maintain. The last is evinced from reports of delayed roll-out of upgrades and of updates (ordinary and security) leading to new problems. Retention of legacy features, particularly superseded ways of doing things, must be a considerable burden.
Windows is not Microsoft's most precious asset: that rests with associated trademarks and various copyrights fronting the Windows cash-cow. Given that customers are not permitted to peer at Windows' nether regions, the cow could be swapped for a bull and nobody need notice.
Therein lies Baldrick's cunning plan. It is to scrape out space within Windows allowing an implanted alien ovum to flourish. This like in the animal kingdom where some insects lay eggs within other insects' bodies and eventually one or more free standing larvae emerge from the corpse of the host. Sleight of hand will ensure that the thing crawling out of Windows, that being a proprietary incarnation of Linux, is Windows so far as the world is concerned. This is accomplished by the embryo, formed from the ovum, gradually encysting legacy Windows attributes such that their requirements can't hinder innovation of the Linux kernel and of deep level software linking it to hardware and to Microsoft's proprietary layers ending with the user interface.
Thusly, Microsoft need not be distracted from what's become its core business regarding office software, and a combined multimedia and vending platform for so-called 'consumers'. Expansion into advertising/government surveillance together with software copyright policing on behalf of client companies will be straightforward so long as 'security' updates remain mandatory.
Meanwhile, individuals and institutions demanding full control of their devices and wary of intrusion will stick with real Linux.
