Hostfiles were used _initially_ on the Internet. Today's DNS was first
proposed in the late 1970s (a couple of years before DOS, never mind
windoze) as a replacement for the Internet hosts files that were maintained
by SRI in Palo Alto and distributed to every host connected to the internet.
The current DNS became the standard in 1983 (two years before windoze 1.0
was in stores - ten years before windoze discovered the concept of
networking - and twelve years before windoze discovered the Internet. The
oldest hosts file available now is RFC0267 from 22 November 1971. Where do
you think microsoft got the _idea_ for a hosts file?

Things were getting out of hand by the mid 1980s. By 1985, there were 185
separate networks (3200 by the end of 1989, just over 72000 now). Can you
imagine trying to maintain a global 'hosts' file today? There isn't even a
global DNS listing - it's a distributed database, with pieces stored on
tens of millions of servers world wide. See RFC1118 for some ancient clues.

Yeah, microsoft still hasn't figured out how to run users with lower
privileges than those needed to screw up the operating system. They claim
to be able to do so, but few systems are operated in that manner, because
this b0rkes so much.
