Microsoft is building Cortana to be an essential part of Windows 10, but it seems that the company doesn’t want you to disable it even if the feature isn’t for you.

Previously, you were able to turn off the assistant with a simple switch of a button, but since the Windows 10 Anniversary Update, the toggle to disable Cortana and turning off the Privacy settings no longer works. However, it’s still possible to disable Cortana by modifying the Registry or using Group Policy.

Although Cortana continues to improve with every update, Microsoft has been restricting the ways you can customize the experience. For example, Cortana only uses Microsoft Edge to show a search, and you are limited to only use Bing as the search engine, and now the company is even removing the ability to turn off the feature.

In this guide, you’ll learn the steps to disable Cortana on Windows 10 using Group Policy or Registry, if this is a feature you never use and don’t want to keep it enabled.
