utility

In computers, a utility is a small program that provides an addition to the capabilities provided by the operating system. In some usages, a utility is a special and nonessential part of the operating system. The print "utility" that comes with the operating system is an example. It's not absolutely required to run programs and, if it didn't come with the operating system, you could perhaps add it. In other usages, a utility is an application that is very specialized and relatively limited in capability. A good example is a search-and-replace utility. Some operating systems provide a limited capability to do a search-and-replace for given character strings. You can add a much more capable search-and-replace utility that runs as an application program. However, compared to a word processor, a search-and-replace utility has limited capability.

Is a utility downloadable to be added to a computer?

Yes. An antivirus is an example of utility software you can download. Just search for the desired software in your browser and you should find variations of it!

And im sure that your OS does have utility software due to every OS having utility software unless you made it yourself but then again you would probably know the answers to all the questions about tech possible to answer.
