One of the major features in Windows 10 is the universal search, you’re new to Windows 10 and you don’t know what universal search is; it’s the ability to search both your computer and the internet from the search bar / Cortana that’s very helpful and handy but some might not like it as they just need results just on the computer and the internet search results are irrelevant, also the internet search results might be very confusing for the elderly. So it might be good to disable the universal search feature.
