Is an operating system necessary for a computer? An operating system is the most essential program that allows a computer to run and execute programs. Without an operating system, a computer cannot be of any important use since the computer’s hardware won’t be able to communicate with the software.

Is it possible to use a computer without an operating system?

You can, but your computer would stop working because Windows is the operating system, the software that makes it tick and provides a platform for programs, like your web browser, to run on. Without an operating system your laptop is just a box of bits that do not know how to communicate with one another, or you.
