How to disable Cortana in Windows 10

Cortana is annoying because it’s essentially a personal data collection service poised as an assistive technology, when its main function is to report that personal information to Microsoft who I believe to be one of the major parties involved in Big Brother-type surveillance and upcoming “crime prediction.”

You can try to disable it via task manager or regedit, but those methods don’t work. You have to attack Cortana’s brain which is contained inside this directory path:


Right click on that Microsoft.Windows.Cortana_cw5n1h2txyewy folder, then click “properties.”

Click the “security” tab, then the “Advanced” button.

In the header, you will see that the file is owned by “TrustedInstaller.” Click “change”, then type “Administrators” into the text field box. Click “ok”, then close all those pop-up windows.

Right click on the Microsoft.Windows.Cortana_cw5n1h2txyewy’s folder again, click the “security” tab, the the “advanced” button again.

Now, look in “Permission entries” and click the “Administrators” entry that has the “access” value as “Full Control.”  Click “change permissions”, select the “Administrators” entry again, then click “Edit.”

Click the “Full control” radio button and click “ok.” You can exit out of the pop-up windows.

Now, open task manager with the hotkey command CTRL+ALT+DEL. Open a file explorer window and open the Microsoft.Windows.Cortana_cw5n1h2txyewy folder. Locate the “Cortana.Core.dll” file.

Now, you have to be quick to delete this file because you have to “end task” for both Cortana applications in the Task Manager, then quickly delete the file before Cortana starts back up. If the file is being used in Reminders WinRT Server, close that program and try again.

Et voila! No more nasty AI.

The taskbar’s search function will end, however, you can still search the old way via an open File Explorer window.
