Vista is stuff because most of the games you try to play on it ar in-compatible. And my father is always getting viruses and having to reinstall the whole os
It's unfortunate, yes, But games no longer working cannot be helped. Technology changes all the time, and trying to keep backwards compatibility with games from 20 years ago would just hinder development and cause problems in the long run.
And getting viruses is not the OS's fault, It's the users.
