Microsoft&#x27;s new CEO is much smarter than these.They are shifting their product to be IT company rather than a pure software company.
They will put endless money on bing. They did put Bing in the core of their best product -Windows 10-.<p>Google does know very well this Microsoft is going to hurt them really bad.
The recent news about Google working on Desktop OS is google&#x27;s answer to Microsoft moves. Microsoft prepares itself  to make greatest Desktop OS in the whole market in next 3 year.<p>And Google does know if Microsoft unifies all its user under windows 10 and windows do provide them best desktop experience, eventually they will find a way to take away user from Chrome(browser)&#x2F;Android to their own platform.<p>The only move google can make in this position, is to work on windows replacement. (and as news came out, they are doing).<p>and they choose android rather than Chrome os to be their desktop os. Let&#x27;s not kid ourselves, chrome os will not be mainstream os maybe until 30 years . (the networking technology is not there yet, it doesn&#x27;t have anything to do how great&#x2F;secure is Chrome OS).At the other hand they had android.which is fragmented, which is not that great. but they have a huge userbase. 
And they are working on a desktop version of android.
