Cortana is your cloud-based personal assistant that works across your devices and other Microsoft services. Depending on the capabilities of your device and the version of Cortana youâ€™re using, Cortana can provide a range of features, some of which are personalized. Cortana on Windows is available in certain regions and languages. If Cortana isnâ€™t available for your Windows device, you can still search for files on your device in the search box on the taskbar. Cortana is also available on other platforms, such as Android and iOS, in select markets.
Cortana works best when you sign in and let her use data from your device, other Microsoft services, and third-party services you choose to connect. To provide you with personalized experiences, Cortana learns from certain data about you, such as your searches, calendar, contacts, and location. Youâ€™re in control of how much data you share. If you choose not to sign into Cortana on Windows, you can still chat with Cortana and use her to help you search the web, documents stored in Microsoft services like OneDrive, and your Windows device. See the section about Windows Search in the Privacy Statement for more information. If you donâ€™t sign in, or you choose to sign out, your experiences will be more limited and they wonâ€™t be personalized with your Cortana data. On iOS and Android devices, Cortana only works when you sign in.
Starting with Windows 10 Creators Update version 1703, Cortana can help you pick up where you left off. When you switch computers, Cortana can display quick links in the Action Center to help you easily get back into Microsoft Edge websites and SharePoint (or other cloud-based) documents you used most recently. For example, if you were working on a PowerPoint deck on your laptop, when you later return to your desktop, a link to that deck appears in the Action Center.
This tutorial will show you how to turn on or off Pick up where I left off in Cortana for your Microsoft account in Windows 10.
