It really wasn't. MacOS classic was full of vulnerabilities as was OS/2 and Linux up through 2004. Windows dominated because it was the biggest ecosystem.
Also, Windows had the ridiculous default of immediately running things when a user put in a CD or USB stick - that behaviour led to many infections and is obviously a stupid default option.
I'm not even going to mention the old Windows design of everyone running with admin privileges on their desktop.
