Windows 11 where is the search box that was in the lower left corner?

Seems like a good place to share this. If you hate the right click menu, open cmd and paste

reg.exe add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve

to restore the old style. Restart/close Explorer. If you want to revert

reg.exe delete "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}" /f

The right-click menu of what?

There are hundreds of right-click menus in various MS products. And various parts of the Win11 UI.

If I’m recognizing the registry key correctly, that restores the Windows 10 context menu in the file Explorer (right mouse button menu on a file in the file list).

The Win 11 version of that menu is abbreviated and hides a lot of common and useful features under a second “more options…” click.

Yes, that’s right, MS dumbed down the Windows Explorer context menu. Using that registry hack was one of the first things I did after upgrading to Win 11.

Explorer

You can also use Shift+Right Click to go directly to the full pop up menu if you don’t like messing with the registry.
