Starting with Windows 10 build 17040, Microsoft added settings that let you to view and manage your activity history. Your collected activity history allows you to jump back into what you were doing with apps, docs, or other activities, either on your PC or your phone. To resume your activities, Windows needs to collect your PC activity.
Timeline is now available in Windows 10 starting with build 17063. In Timeline, a user activity is the combination of a specific app and a specific piece of content you were working on at a specific time. Each activity links right back to a webpage, document, article, playlist, or task, saving you time when you want to resume that activity later.
In addition to resuming past activities through Timeline, your personal digital assistant Cortana will suggest activities you might want to pick up where you left off (resume) to help you stay productive as you switch between your phone, laptop, and other Cortana-enabled devices. This experience is powered by the same activities that appear in Timeline.
Starting with Windows 10 17083, Microsoft added a new setting that allows you to sync your activities to the cloud for a seamless cross-device experience. You can enable Let Windows sync my activities from this PC to the cloud in the settings app, or you can enable it via an option provided at the bottom of Timeline. Until new users enable this setting, Timeline will only show four days of activities. (If you are upgrading from an earlier WIP flight, you may not see this option as the setting is already enabled.)
If needed, you can set a group policy in Windows 10 to allow (enable) or prevent (disable) users from being able to turn on (check) Let Windows sync my activities from this PC to the cloud for their accounts on the PC. This policy setting determines whether published User Activities can be uploaded.
This tutorial will show you how to enable or disable let Windows sync my activities from this PC to the cloud feature for all users in Windows 10.
