How to uninstall Cortana from PC

If you're wondering how to uninstall Cortana from your PC, you've come to the perfect place.

Fortunately, Microsoft is making its digital assistant less and less common on devices like the top-tier Windows laptops, making it quite easy to shut it down.

According to Windows Latest, there are two methods for shutting off Cortana. You may either delete the Cortana program from Windows 10 (which is a little more difficult) or prevent it from starting up automatically when your computer boots up (which is the easier option). However, there are other ways outside the Microsoft world that can completely switch off Cortana Windows 10.

Reasons To Uninstall or Disable Cortana

The following are some reasons for turning off Cortana in Windows 10:

  1. Resource Usage: Cortana is constantly waiting for voice commands in the background. If you have limited resources, this process slows down your system and uses a lot of your RAM. Therefore, to speed up your system, you should turn off Cortana.
  2. Privacy: Cortana requires the gathering and use of user data and personal information to work better for a particular user. If you are uncomfortable with this data sharing, improve your privacy by turning it off.
  3. Personal Preference: Some users may prefer another voice assistant.
  4. Lack of Usefulness: Compared to other voice-activated AI-assistants, users have generally found that Cortana doesn’t do much, as advertised. In numerous test scenarios, it was unable to identify the user's voice and failed to offer helpful details on a particular subject. Therefore, you may easily disable Cortana if you find it to be of little use to you and does not increase your productivity.

How To Uninstall Cortana Without Leaving Any Residual Files

Over the past few years, Cortana has undergone numerous adjustments. With its recent update, you are now receiving a new version that focuses on making you more productive while abandoning many of its features.

The biggest change with Cortana is that it is no longer included in Windows 10, along with the removal of several ineffective features (including Skills and Notebook). It’s not an integral part of the OS; one can just update it or uninstall it and move around from Windows XP to Windows 10 through the Microsoft Store. If, at any time, you don’t find the digital assistant useful, you can easily get rid of (or disable) Cortana on your PC.

1. Third-party Uninstaller App

You can remove or turn Cortana off in Windows 10 using a third-party uninstaller like Master Uninstaller. Follow the steps below to learn how to turn off Cortana and uninstall it completely:

2. PowerShell

You can easily uninstall Cortana from your PC using PowerShell. However, you should take a backup of your important files because it is a tricky method. Follow these steps to uninstall Cortana from Windows 10:

PowerShell run as administrator

After the procedures, Cortana will be deleted. You can right-click the taskbar and remove the Show Cortana button option, but the taskbar button will stay there. Power users who are determined to remove Cortana will, of course, need to delve much further into the Windows Registry, which is considerably riskier for regular users. We advise omitting the section since it is less essential and somewhat risky.
