Why is windows is the leading operating system?

Answer 1

Windows was the first operating system and only operating system for many years. Therefore people know what to expect from it.

Before Microsoft, there were many computers and operating systems. Computers systems were either mainframes including IBM OS, minicomputers, midrange computers, and graphical workstations. They had commercial level operating systems that were used to run businesses, laboratories, schools, etc. All cost tens or hundreds of thousand of dollars or more. None were suitably priced for home use or for office desktop use.

Personal Computers running Microsoft Windows were the first consumer level systems marketed to and available for personal and home use for a few thousand dollars. Being first, they cornered the market and established a name and reputation. There were no competitors at that price range and Microsoft was aggressive in preventing copycats.
