How to completely disable Cortana in Windows 10

Recently, one of my reader asked that after following the above linked guide, he was able to completely disable Cortana. But now he wants to re-enable Cortana on his system. So he asked me how to do that? I just told him to revert the process to get Cortana back. This worked well for him.

That scenario lead me to write this separate article to show you how to reinstall or re-register Cortana with factory defaults. This article will also be helpful to those users, for whom Cortana is not working as expected. Reinstalling Cortana should fix up all the issues associated with it.

So without wasting time anymore, here is how to re-register Cortana:

How To Reinstall Or Re-register Cortana In Windows 10

1. Press W8K + R keys and type %WinDir%\SystemApps in Run dialog box. Click OK.

2. In SystemApps folder, rename Microsoft.Windows.Cortana_cw5n1h2txyewy.old or whatever name it has to Microsoft.Windows.Cortana_cw5n1h2txyewy.

Let the cmdlet execution complete. Once completed successfully, Cortana is reinstalled or re-registered.

NOTE: If you don’t perform step 2 and directly perform step 5, cmdlet execution will fail with below shown error. This is because the execution can’t locate Microsoft.Windows.Cortana_cw5n1h2txyewy folder, which must be present at %WinDir%\SystemApps.

    ^^ You need to do it quickly by giving multiple tries or you can also use recovery mode Command Prompt for this.
