14. Muzzle Cortana
But what if you don’t want Cortana listening in on you whatsoever? Microsoft unfortunately disabled all overt methods for switching off the digital assistant in the Windows 10 Anniversary Update, along with a handful of other things.
There’s still a workaround for closing its eyes and ears though: log out of your Microsoft Account in Cortana. To do so, head to Notebook > About me > User account > Sign out. This will severely limit functionality, though. Alternatively, you can limit Cortana’s awareness and use a third-party local search tool.
