well from my narrow perspective, as it is all business
why make good OS/product when you can make crap, then sell it, then make it fancier and maybe tweak thing here and there, then sell as "better version"
and then slowly introduce something that is in fact old but for their ecosystem is new (example with native PDF reading, MKV files, mounting virtual iso's)
and again sell it as something revolutionary... etc...
to me MS will only update drivers and hw support, but as OS itself it is waaay behind...
but at the end its all money that counts... they stopped giving two bit s*** what ppl want/need long ago
they get some exclusive right sales from US goverment most likely coz they bent over for free trojan insertions
it just bleeds money money money
