Quote:The Privacy dashboard on Microsoft's website lists recent activity, e.g. visited sites or started applications, even if Activity History is disabled on a Windows 10 device.

Recent versions of Microsoft's Windows 10 operating system support a feature called Activity History that is keeping track of some of the things that users are doing on the device so that they may "jump back".

Activity History powers the operating system's Timeline feature. Timeline, which you may invoke with the shortcut Windows-Tab, displays a timeline view of activity when opened.

Only some applications such as Microsoft Edge or Office applications support it at the time. The main idea behind the feature is to display a history to users similarly to browsing histories of web browsers.

It is easy to go back to a particular application or re-open a website using the feature.

Three main options are exposed to users and administrators in the Settings application:

• Store my activity history on this device.
  
  
• Send my activity history to Microsoft.
  
  
• Show activities for specific accounts.
  

The first keeps track of activity on the device, the second sends it to Microsoft.
