How to Fully Disable Cortana Virtual Assistant in Windows 10 OS

  1. Open the Registry Editor (regedit)
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell
  3. Create a new 32-bit DWORD value named EdgeUiDisabled and set the value to 1
  4. Restart your computer

This will disable all edge swipe gestures including the one that opens Cortana.

Uninstall Cortana

As suggested in the search results, you can fully uninstall Cortana:

  1. Open Programs and Features
  2. Click “Turn Windows features on or off”
  3. Uncheck the box for Cortana
  4. Click OK and let Cortana uninstall

While effective, this will completely remove Cortana from Windows.

Disable Cortana Touch Gestures

You can specifically disable the touch gestures to open Cortana:

  1. Open Registry Editor
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
  3. Create a new DWORD value named DisallowCortanaAboveLock
  4. Set the value to 1
  5. Restart your computer

This will leave Cortana installed but disable it from being opened with touch gestures.

I’d recommend trying the last method first to specifically target the gesture opening Cortana without fully removing it. Let me know if you have any other questions!
