Cortana, a novelty (marketing?) delivered with Windows 10 allows you to search directly from the taskbar and with the help of the Cortana voice assistant (a Siri equivalent for Windows). If you are not a fan of this feature, learn how to disable it without further delay.
The first step is to rename the folder containing the Cortana application. For this, a small quick handling will be necessary.
Go to the file C:\Windows\SystemApps
Right-click on the folder Microsoft.Windows.Cortana_cw5n1h2txyewy then Rename.
Enter a new name for the folder (example by adding OLD) and do Entry.
An error message tells you that this is not possible. Do not close the dialog box.
Open the task manager via CTRL+ALT+ECHAP. On the tab Process, right-click on Cortana in the list then End of task.
Immediately after, in the dialog box that we left open, do Retry. If you have been fast enough, the file is renamed. If the message still appears, repeat the operation by being faster.
The last step is to hide from the Cortana taskbar (search box).
To do this, right-click on the taskbar, and click on Find then Masked.
Admire the result:
And that’s it, Cortana’s completely disabled. It will no longer go into a background task, freeing some system resources as they pass, and above all, will no longer burden your task bar.
