http://en.wikipedia.org/wiki/List_of_operating_systems
This is a list of notable operating systems. Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. Criteria for inclusion is notability, as shown either through an existing Wikipedia article or citation to a reliable source.

These tables compare general and technical information for a number of widely used and currently available operating systems.
Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed comparison. There are also a variety of BSD operating systems, covered in comparison of BSD operating systems. For information on views of each operating system, see operating system advocacy.
