If you’re using a Windows 10 machine, you might want to consider disabling Cortana — at least on the Lock Screen — if you aren’t planning to install the latest Windows updates for whatever reason. (And, generally, do you really need a smart assistant helping you out when your PC is locked?)

McAfee security researchers recently discovered that Cortana could be summoned from Windows 10’s lock screen and used to execute malicious software, The Verge reports.

Of course, someone would need physical access to a computer in order to perform the hack, but it would allow the person to launch files from a USB stick — and the sky’s the limit after that.

McAfee recommends users run Windows Update to get Microsoft’s latest security patch, which corrects the issue. However, if you aren’t planning to, or need a bit of time before you can run the update, you can always just disable Cortana on your Lock Screen to circumvent the hack.

To disable Cortana on the Lock Screen, launch the assistant by clicking on the circle icon to the left of the search bar on your taskbar. Click on the gear icon on the left pane, and then look for the “Lock Screen” section.

Untick the option to “Use Cortana even when my device is locked,” which isn’t the worst idea in the world anyway — even though Microsoft has patched the hack, do you want anyone to be able to chat with your desktop or laptop when you aren’t using it?


  • I just wish I could replace it with Google’s Assistant (without installing chrome extensions or installing other software)

  • Not gonna work because windows mark their basic programs as safety environment so they will be reactivated anytime. Just got the right key.

  • I just wish you didn’t have to launch cortana in order to say you don’t want to use cortana. That’s pretty stupid.

    Same thing with Samsung’s Bixby.
