An operating system
Usually I'm transparent, keep me clean.
Windows, the most common operating system
Sometimes I'm generated by a fruit, keep me intact.
MacOS or iOS, made by Apple
Sometimes I'm a penguin, keep me fresh.
Linux, its symbol is a penguin
Sometimes I'm in Star Trek, keep me in the future.
Sometimes I shine like the sun, keep me clear.
Rarely I'm something else.
Those are the most common operating systems. Anything else is pretty rare.
And remember, you own me for sure!
Anyone answering this question must own (or at least be using) an operating system of some sort.
