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 Home
Hit the Start Key, search for regedit, and open it.
Navigate to HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft > Windows.
Right-click the Windows directory, and choose New > Key.
Type in Windows Search, and hit enter.
Select Windows Search. In the right-hand side pane, right-click in the empty area and choose New > DWORD (32-bit) Value. Type in AllowCortana, and hit enter.
