🧩 Method 3: Disable Cortana via Registry Editor (All Windows 10 Editions)

1. Press Windows + R, type regedit, and hit Enter.

2. Navigate to:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search


   • If Windows Search doesn’t exist, right-click Windows → New → Key → Name it Windows Search.
