Make sure you’re running the latest version of Windows. That way, you’ll have the newest features, like timeline, and the latest security protection. To check:
On your PC, select the Start button, then select Settings > System > About. Your PC should be running version 1803 or later.
If your PC isn't running version 1803 or later yet, select the Start button, then select Settings > Update & Security and select Check for updates to install the latest version of Windows 10.
You’ll also want to be sure that the Task View wasn’t accidentally turned off. To check:
Right-click a blank spot on the taskbar.
Select the Show Task View button.
Using your work PC? Check with your organization’s IT administrator to see if timeline is allowed.
Timeline may only display 3-4 days of activity if you just set it up. If you sign in to your PC using a Microsoft account – the account you use to sign in to services like Office 365, OneDrive, and Skype – you’ll soon see up to 30 days of activities.
Double-check your timeline settings by selecting the Start button > Settings > Privacy > Activity history, then select the check box next to Let Windows collect my activities from this PC and Let Windows sync my activities from this PC to the cloud.
It’s important to note that not all apps support timeline yet, but developers are hard at work creating high-quality activity cards for it. In the meantime, you’ll see activities in your timeline from opening files in apps like Microsoft Office (Word, Excel, PowerPoint, and OneNote), or browsing the web in Microsoft Edge.
If you’re using another PC with an older version of Windows, activities from that PC won’t show up in your timeline.
It could be because the app that you used to create an activity – let’s say, Microsoft Word – isn’t installed on the PC you’re currently using to view timeline. Also, documents can’t be opened if they were moved, deleted, or stored on a different PC than the one you’re currently using.
If you try the troubleshooting steps and are still having issues with timeline, use the Feedback Hub app to let us know. You can even attach some screenshots or recreate a problem to help us see what you’re experiencing.
To open the Feedback Hub app, select the Start button, and then select Feedback Hub.
If you haven’t download the Feedback Hub app, select the Start button and select Microsoft Store from the app list or select it from the task bar. In Microsoft Store, type Feedback Hub in the Search box, and then select and download the app.
