Total Recall:

‘The first of those new features is called Recall, and Microsoft says it's like a PC with "photographic memory." The feature remembers everything you do on your computer, allowing you to quickly "recall" something regardless of whether it was an email you read, a website you visited, or a document you examined. You can control how long the timeline for these memories is and remove certain sites from being cataloged. All the data stays on your PC for enhanced security.’
