I did both of these:
- To disable web search in Start on Windows 11, open Group Policy (gpedit.msc) > User Configuration > Administrative Templates > Windows Components > File Explorer, open and enable the “Turn off display of recent search entries in the File Explorer search box” policy.
- Alternatively, open the “HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows\Explorer” path in the Registry, create the “DisableSearchBoxSuggestions” key, and set it to “1.” If it's hidden, open Regedit as admin.
