Microsoft has integrated Bing web search in Windows 10/8.1, in addition to the native search available in previous Windows editions. Thus when you search for anything on your Windows computer, if you’re connected to the web, Bing web search results are displayed automatically. This is continued with Windows 10, and here Cortana – the voice assistant leads the flag.
Now, some users may be okay with the fact that web results are displaying additionally even when they don’t look forward to them. However, some other communities of users may not be convinced of this fact. The reason behind this could be unnecessary data consumption by your system to fetch web search results. Thus, if you also belong to the latter community of users, you may want to disable web search results completely from being displayed in Windows 10.
UPDATE: Since since Cortana is separate from Windows Search, Windows 10 v2004 and later may have to follow this procedure to disable Bing Search in Windows 10 Start Menu.
