Final answer:
Salt is a configuration management tool that supports Windows and Unix-like systems, but it is more commonly used with Unix-like systems due to Unix's historical relevance in computing and networking.
Step-by-step explanation:
The question pertains to Salt, a popular automation and configuration management tool, which supports both Windows and Unix-like operating systems. Although Salt can manage Windows systems, it is more natively aligned with Unix-like environments. This is because Unix, particularly in its commercial forms, has a long history in the context of networking and computing. The evolution from a more open Unix system to commercial versions, such as IBM's AIX, Microsoft's Xenix, Sun Microsystems' Solaris, and SGI's IRIX, illustrates the move towards proprietary systems. These systems have their roots in the original UNIX developed by AT&T Bell Labs and the University of California, Berkeley, showing a trend of open resources becoming commercialized over time.
