Microsoft doesn’t allow you to Disable Cortana. You wont to be able to turn off Cortana in Windows 10, however, Microsoft removed that simple on/off switch within the Anniversary Update.
However, it is possible to disable Cortana via a registry hack or group policy setting. This will transforms the yours Windows system Cortana box into a “Search Windows” tool for local application and file searches. It was like in Windows 7 or 8.
Cortana has become more and more restrictive since Windows 10’s release. It was recently updated to ignore your default web browser.
Currently, Cortana continuously launches the Microsoft Edge browser and only uses the Bing search engine when you search. If that sounds like something you don’t need to use.
Here’s the way to turn it off.
Disable Cortana in Windows 10 Home via the Registry:
If you have Windows 10 Home, you must edit the Windows registry to make these changes.
You can also use this little hack trick if you have Windows 10 Professional or Enterprise, but make sure you’re more friendly & comfortable with the Windows registry as opposed to Group Policy Editor.
(If you have Pro or Enterprise, however, we recommend using the Easy Group Policy Editor described in the next section).
Standard warning: Registry Editor is a powerful tool and its misuse can destabilize or even disable your system. This is a very simple hack and as long as you stick to the instructions, you should have no problem.
Having said that, if you’ve never worked with it before, consider reading about how to use Registry Editor before getting started. And of course, back up the registry (and your computer!) Before making changes.

You should also create a system restore point before continuing.
