Cortana used to be Microsoft’s star digital assistant, designed to rival Siri, Alexa, and Google Assistant. But in Windows 11, Cortana has been pushed into the background, and most people hardly use it anymore.
In fact, many users find Cortana unnecessary or even annoying. It runs in the background, consumes system resources, and occasionally interrupts with voice prompts. The good news? You can easily disable Cortana in Windows 11.
In this step-by-step guide, I’ll show you different methods to turn off Cortana completely—whether you just want to stop it from launching at startup or remove it altogether.
Why Disable Cortana in Windows 11?
Before we dive into the how-to, let’s look at why you might want to disable Cortana:
Performance boost: Fewer background apps = faster startup and smoother performance.
Privacy concerns: Cortana collects voice data and search history.
No real use: Many users prefer Google Assistant or Alexa.
Annoying pop-ups: Cortana sometimes interrupts with suggestions.
If any of these sound familiar, you’ll be happy to know you can take control.
