How to Add or Remove Cortana from the Windows 10 Lock Screen

As of the Windows 10 Anniversary Update, Cortana is available from the lock screen. Without taking the time to log in, you can use Cortana to get the latest weather report, check on an upcoming flight or set a reminder that syncs with your phone. If you're willing to lower the security level, you can also allow Cortana on the lock screen to send email and texts or add events to your calendar.

You can access the assistant when the display is locked by either saying "Hey Cortana," or tapping a dot on the display. While the former is a useful option if your hands are busy, the latter is a better choice if you want to reduce how often you speak to your computer. Here's how to setup Cortana on your lock screen, tweak its settings or disable it.

How to Enable or Disable Cortana Access on the Lock Screen

1. Select the Ask me anything field.

2. Select the Gear icon.

3. Turn Lock Screen on or off. It may already be enabled. If you turn it off, skip the remaining steps.

4. Check "Let Cortana access my calendar, email..." if you want the digital assistant to be able to send emails, book appointments or send SMS messages from the lock screen. This could be a security risk if a bad actor gets access to your computer while you're away.

5. Enable Hey Cortana if you want to launch Cortana from the lock screen with your voice. If you'd prefer to launch the assistant with an icon tap, see below. Either way, you're going to end up talking to your computer, however.
