When Windows 10 originally launched, Cortana—Microsoft’s answer to Apple’s Siri and Amazon’s Alexa—was deeply integrated into the operating system. It occupied a massive chunk of the taskbar and constantly listened for voice commands. However, as the digital assistant market shifted, Microsoft fundamentally changed its strategy.
In Windows 11, Cortana is no longer a core system feature. It is now a standard, standalone application. It does not live on the taskbar, and it does not listen in the background unless you specifically open the app and log into it. In fact, as of late 2023, Microsoft officially ended support for the standalone Cortana app entirely, replacing it with the new AI-powered Windows Copilot.
If you are still seeing Cortana pop up, or if the app is launching itself automatically when you turn on your PC and draining system resources, you can easily disable it or uninstall it completely.
Method 1: Stop Cortana from Opening at Startup
If the main issue is that the Cortana window stubbornly opens on your screen every time you boot up the computer, you simply need to revoke its startup privileges.
- Right-click anywhere in the empty space of your Windows 11 taskbar.
- Select Task Manager from the pop-up menu. (Alternatively, press Ctrl + Shift + Esc on your keyboard).
- In the Task Manager window, look at the left-hand sidebar and click the Startup apps icon (it looks like a speedometer gauge).
- Scroll through the list of applications until you find Cortana.
- Look at the “Status” column next to Cortana. If it says “Enabled,” the app is turning itself on automatically.
- Right-click on Cortana.
- Select Disable from the context menu.
The status will change to “Disabled.” You can now close the Task Manager. The next time you restart your PC, Cortana will remain completely dormant.
Method 2: How to Uninstall Cortana Completely
Because Microsoft has deprecated the assistant, there is absolutely no reason to keep the dead application installed on your hard drive. However, because it is a “system app,” Windows 11 will not let you uninstall it via the standard Add/Remove Programs menu; the “Uninstall” button is greyed out. You must use a single, simple command line to remove it.
- Click the Start button and type Terminal or PowerShell.
- Right-click the Terminal app in the search results and select Run as administrator. (Click “Yes” on the security pop-up).
- A blue or black command window will open.
- Copy and paste the exact following text into the window:
Get-AppxPackage -allusers Microsoft.549981C3F5F10 | Remove-AppxPackage - Press Enter.
The command will run silently for about two seconds, and a new command line prompt will appear. That’s it. You can close the window. Cortana has been completely eradicated from your Windows 11 installation.
