By default in Windows 10, when a user enters a phrase in the search box, Windows will display results from both the computer and the Bing search engine. So if you are looking for a specific folder or file on your computer, Bing results can be an unnecessary distraction.
As usual, Microsoft did not provide a simple way to disable Bing search engine results.
To disable Bing results from Windows 10 searches, you need to edit the Windows registry file. However, editing varies depending on the version of Windows 10 you have installed.
The March 2020 Update of Windows 10 requires the creation of a new key in a specific location. Earlier versions of Windows 10 required the creation of a new key in a different location.
Here's how to turn off Bing results from a Windows 10 search.
If you are running the March 2020 Update of Windows 10 or later
Type "regedit" in the Windows 10 search box and select Registry File Editor from the list of results. Then follow the route:
HKEY_CURRENT_USER \ SOFTWARE \ Policies \ Microsoft \ Windows \ Explorer
To create the new key, right-click the Explorer folder and select New | DWORD value (32-bit). Name the new key DisableSearchBoxSuggestions as shown below:
Now, double-click the DisableSearchBoxSuggestions key that you just created and change the Value Data box to 1, as shown below
Close Registry File Editor. You must restart your computer (or Windows Explorer) for the change to take effect.
If you are running a version of Windows 10 older than the March 2020 Update, follow the path:
HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Search
To create the new key, right-click on the Search folder and select New | DWORD value (32-bit). Name the new key BingSearchEnabled as shown below
Now, double-click the BingSearchEnabled key you just created and change the Value Data box to 0 (zero), as shown below
Also in the Search folder is a key named CortanaConsent. Double-click this key and change its value to 0 (zero), as shown below
Close Registry File Editor. You may need to restart your PC or Windows Explorer to see the change.
To add Bing results to your computer searches, change the value data for each key to 1.
