rem * Cortana was the old AI feature in Windows 10 and 11
rem * Copilot is the new AI for Windows 11
rem * Recall is the regular screenshot system in Windows 11 24H2 (and future builds?)
rem
rem I find all of these to be either not useful, or huge security problems.
rem So let's disable them all.
rem 
rem This will work on Windows 10 as well, though it only has Cortana.
rem

rem
rem --- DISABLE CORTANA ---
rem 

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows\Windows Search" /v AllowCortana /t REG_DWORD /d 0 /f > nul

rem
rem --- DISABLE COPILOT ---
rem 

reg add "HKCU\Software\Policies\Microsoft\Windows\Copilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 1 /f > nul
reg add "HKLM\Software\Policies\Microsoft\Windows\Copilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 1 /f > nul

rem
rem Seen keys as both "Windows\Copilot" and "WindowsCopilot", so doing
rem it both ways.
rem 

reg add "HKCU\Software\Policies\Microsoft\WindowsCopilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 1 /f > nul
reg add "HKLM\Software\Policies\Microsoft\WindowsCopilot" /v "TurnOffWindowsCopilot" /t REG_DWORD /d 1 /f > nul
