By default, Windows sends everything you type in the Start menu to Bing for web results. This means every time you type a program name to launch it, you’re also sending a search query to Microsoft’s servers. The web results clutter the search panel and slow down local results.
This command disables Bing search integration and Cortana consent in the registry. After applying it, Start menu searches only show local apps, files, and settings — which is almost always what you actually want.
The change takes effect on the next Start menu open. No restart or sign-out required.
