Security experts have warned about a major security flaw in Windows 10 that could allow hackers to bypass the password on your computer and access private files.

The Microsoft voice assistant is built into every version of Windows 10 and is designed to schedule calendar appointments, check the weather, set reminders, send emails, and more. However, the new security flaw could enable hackers to browse files, install a virus, and even reset your password – locking you out of your own machine. The flaw allows criminals to invoke the Cortana desktop menu from the lock screen – when the computer is supposedly secure – and use it to trawl files on the system.
