A search box does not display in all windows

A search box can be described as a field that is present in all computers. Keywords can be inputted in a search box to look for a particular app, file, folder or document.

A search box helps to make work easier, with a search box instead going to the menu an searching for a program/document. You ca easily just type in what you want and it is brought out within seconds.

One function that a search box doesn't do is that it doesn't display in all windows.

The answer is option 4. Displays in all windows

A search box acts as a field for a query search for the user to retrieve information from the database. A search box supports instant search whenever possible and returns relevant results within a few seconds.  So option 1 and 2 are correct. You can retrieve your files and folders hidden anywhere on your operating System by quickly doing a search from the start menu. This leaves us with the last option as the correct answer.
