It looks like there is a new codename on the Microsoft roadmap, it is called Redstone. From what we are hearing it will be a large update to Windows 10 expected in 2016. Windows 10, which was codenamed “Threshold” is to be released this summer. In the fall there is going to be a large update to Windows 10, which will still be called Threshold. This will be in addition to smaller and regularly released updated and fixes.
Last week we had confirmed that Windows Blue will be called Windows 8.1 and would be an update to Windows. We now know this update will be free through the Windows store and will not be a service pack. It seems like Microsoft is finally getting it and offering seamless and free OTA (over the air) updates for their operating system.
