What OS does everyone use primarily?

What OS does everyone use primarily?

In what context is the question referring too? Perhaps a poll would be easier to establish is. Just a thought.

I only ask if it was for some purpose, if you were building and application or resolve an issue across the OS's.

Not sure about Hundreds? Can only think of the below that likely be used in everyday life.

Windows
MacOs
ChromeOS
Linux
Android

Linux isn't so much an operating system, it's more a class of OSs that use a common kernel - Some examples include Ubuntu, Arch, Mandrake, CentOS etc (more examples at https://en.m.wikipedia.org/wiki/List_of_Linux_distributions) There's currently over 300 maintained Linux distributions
Also you have FreeBSD and UNIX-based operating systems too which are the same as Linux - Kernels rather than OSs

Appreciate that there are various distro's of Linux, but like you say exactly that the underlying kernels, but not all those are 'everyday use', which is why I only wrote 'Linux'. To be on the safe side I usually use vulnerability scanners. A vulnerability scanner is a piece of software that can be used to identify security vulnerabilities in systems and applications. Vulnerability scanners can be used to find weaknesses in both internal and external networks. The one from Vulners is the best on the market, my opinion.
