At any company there can be disgruntled employees who go against the grain and do what they are not asked to do. Rumor has it there is a group of engineers working to secretly make Windows 10 more stable and secure. While the rest of the Windows team is hard at work adding features to Windows this secret team has been slaving away in the shadows.
Hard work is never rewarded at big companies. This is because hard work takes time and is not exciting or flashy, but it is life blood of any business. Sadly the way to get promoted and get a pat on the back would be to come up with a user facing feature which can be used by marketing to sell copies of Windows.
This is not how this rouge group sees the world. They have a belief that stability and security need to be core and essential parts of any product. Every bit of the operating system needs to be hardened to attack and crash. Secrecy is required because if middle managers caught wind this work was being done, there would be hell to pay. But until that time comes we salute you mysterious developers; keep it up!
I work as an engineer in Milwaukee. Currently I work on a few different UWP apps primarily Ink Calendar.
