Much simpler is to just paste to a terminal:
REG ADD HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Search /v BingSearchEnabled /t REG_DWORD /d 0 /f
REG ADD HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Search /v CortanaConsent /t REG_DWORD /d 0 /f Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Search]
"ConnectedSearchUseWebOverMeteredConnections"=dword:00000000
"AllowCortana"=dword:00000000
"DisableWebSearch"=dword:00000001
"ConnectedSearchUseWeb"=dword:00000000
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search]
"CortanaConsent"=dword:00000000
"BingSearchEnabled"=dword:00000000
"AllowSearchToUseLocation"=dword:00000000
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search] "BingSearchEnabled"=dword:00000000 "CortanaConsent"=dword:00000000
^ put this into a .reg file, run it, and never see those bullshit web search results again. Have been doing this first thing after a fresh install on every PC.
