You definitely want to change these Windows Settings from their default.
Here's the command prompt command to remove web results from start menu searches:
reg add "HKCU\SOFTWARE\Policies\Microsoft\Windows\Explorer" /v DisableSearchBoxSuggestions /t REG_DWORD /f /d 1
To put it back to default, change the last one (1) in the command to a zero (0)
Windows 11 has a ton of default settings that are pretty annoying or just not ideal. A lot of them are privacy settings, but there's also a bunch for convenience or for features that aren't even enabled by default. In this video I go over a bunch of the easy low-hanging-fruit you can change to improve things.
I show you exactly where to find them and what to change, whether it's enabling or disabling each one.
