Microsoft has made its digital personal assistant Cortana have more integral to Windows 10 with every major update. Apart from searching your computer, it displays notifications, can send emails, set reminders, and do all of that using your voice. Some might find it too intrusive though and would prefer to turn the helper off. While you could turn off Cortana with a single toggle in the days before the Anniversary Update, that’s no longer possible. And with the recent Windows 10 Creators Update, disabling Cortana can entirely break search, according to reports, with the only way to fix it being a clean install.
How to Disable Cortana on Windows 10
Click the search box or the Cortana icon next to the Start key.
Open Cortana’s settings panel with the gear icon.
In the settings screen, turn off every toggle from On to Off.
Next, scroll to the very top of the settings panel, and click on Change what Cortana knows about me in the cloud.
Microsoft will fetch a page from the Internet called Personal Information in the same Start panel.
When it loads, scroll to the very bottom, and hit Clear.
