How to Disable Web Suggestions and Search Highlights
You can use the search box to find your apps, files, settings, help, and more on Windows. Also Microsoft added start menu search bar search highlights to feature social events and other “trending” searches. Search highlights is a feature that helps you discover interesting content whenever you launch Windows Search. But for some, search highlights can be distracting. If you find them to be bothersome, well, you can turn them off and continue enjoying Windows as if they never existed.
How to Turn Search Highlights On and Off in the Settings App
Windows Settings menu, go to Privacy & security > Search permissions.
Then scroll down to “Show search highlights.” Toggle this to the “off” position.
