If you only want to search for local content, the web search results included in Windows 11 may just be interfering items, then you can try the following methods to disable it
Since Windows 10, Microsoft has introduced the search result from Bing in addition to local apps, files and settings. Needless to say, this feature is not very popular in most cases, because when you use Windows search bar to find something on your computer, all that pops up is probably useless information from Bing, which greatly reduces the efficiency of your search.
Windows 11 has made radical changes to the system, but unfortunately, Win10's annoying web search has been inherited in Win11. At the same time, Win 11 also forced to lock the search network results using the "microsoft-edge://" protocol, and cannot be modified, which means that even if you set another browser as the default, it will still be forced to use the Edge browser to open.
What should you do if you don't like this setting? Now, we'll show you how to turn disable Bing search in Win11.
First, we need to open the registry. In Windows Search, search “registry” directly and open Registry Editor.
Next, go to the following path in the registry.
Right-click on "Windows" and select "New".
Create a new key named "Explorer" and press the Enter key.
Then, right-click on the Explorer item and create a new DWORD (32-bit) value.
Name the new value "DisableSearchBoxSuggestions" and press the Enter key. In this way, you can control whether to switch on and off the network search or not.
At this point, it's easy to turn off the network search in Win11. Double click on the DisableSearchBoxSuggestions value and assign it a value of "1".
Then save the registry, restart the computer, open the system search again, and you will find that no network results will be searched anymore!
In general, the system search of Win10 and even Win11 pushes Bing engine, and there is no option to turn it off, which bothers many users. If you also encountered this problem, you can try the method above.
