Microsoft just realeased Windows 10 Insider Preview Build 17127 for PCs in Fast Ring. The announcement of this build (Redstone 4 branch, will be Windows 10 version 1803 next month) was made as usual within the Windows Blog.
The new build introduces several Cortana improvements like a new profile page. Microsoft is introducing a new server-powered profile page in Cortana for you to add and edit your favorite places. The places you add are used to give you traffic updates for your daily commute, and let you easily set reminders when you arrive or leave your places. To get to this page, head to the Notebook section of Cortana and click the button to the right of your name. This is available for all Cortana markets.
Also Cortana’s new Notebook goes international with improved performance. The Windows Mixed Reality Team has fixed most of the issues in previous builds. And there are new Windows Mixed Reality features. Details may be found within Microsoft’s blog post.
