In a week where AMD, Intel and Qualcomm have already made major announcements, Microsoft’s keynote yesterday at Computex in Taipei was relatively low key. Instead of revealing new products, the company hinted at what it wants in a modernized operating system. Intriguingly, Microsoft’s blog post about the keynote does not mention Windows, lending credence to speculation that it is developing a new “super-secure” OS.

According to the blog post by Nick Parker, corporate vice president of consumer and device sales, a modern OS should enable “form factor agility” by being flexible enough to be integrated into different types of devices, which is noteworthy because last year the company hinted at new additions to the Surface lineup, which some have speculated might mean the line is adding a smartphone.

He added that a modern OS should include seamless updates, done invisibly in the background without forcing people to stop using their computers and be secure by default, preventing attacks by separating the state from the operating system and the compute from applications.

A modern OS would constantly be connected to LTE 5G and use AI to help make apps more efficient. It would also support different kinds of input, including pen, voice, touch and even the ability to use your eyes to control apps or write — two things likely to fuel more speculation that the new OS will be developed with mobile products (like a possible Surface Phone) and lightweight or dual-screen laptops in mind.
