Windows Timeline is out of the Fall Creators Update for now
The Windows Timeline feature was announced during Build 2017 alongside a slew of consumer and developer features slated to arrive in the next major update for Windows 10: the Fall Creators Update. However, Microsoft's Corporate Vice President in the Operating Systems Group, Joe Belfiore, tweeted that the Windows Timeline feature has been pushed out of the Fall Creators Update (FCU). It will however, soon start appearing for Windows Insiders in OS builds succeeding the FCU.
Windows Timeline uses the Microsoft Graph API to intelligently bring content across Windows, iOS and Android devices to help users work agnostic of the platform. It also brings with it the Pick Up Where You Left Off feature of Cortana and a cloud-powered Clipboard. So, you can now start working on a Word document on the PC, log off, and resume it on your phone or tablet at exactly the same instance. This extends across all connected Microsoft services. The Windows Timeline lets you see what you have been working on over a period of time across all your devices and enables you to hop back and forth without having to transfer or share files between them.
Joe Belfiore clarifies that the feature would not ready by the time FCU launches in October. Actually, no timeline for the feature was specified during the Build conference. Insiders who have been testing recent Windows 10 builds say that Windows Timeline is far from complete and is right now, just a glorified front-end showing recent activity. This is not the first time Microsoft has deferred announced features for future releases. The MyPeople experience, which provides easy access to contacts from the taskbar itself, was originally supposed to debut in the Creators Update but that has now been slated to appear in the FCU.
