With the newest update, windows has hidden the option “search online and include web results” and therefore has made it difficult for users to disable Cortana and Web results completely.
Luckily for us there is a relatively easy fix.
- Type Win + R to open run and type in gpedit.msc
- Go to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Search
- Disable “Allow Cortana”
- Enable “Do not allow web search”
