3.
an operating system which uses more RAM than the typical system and automatically installs Microshaft's own Internet Expirer browser on your system, then won't allow you to remove it, thus allowing Bill Gates to view your system personally. It also self-upgrades, thus taking up your memory with Borg implants. Did I mention that some versions uninstall all non-MS products? Also expect to view the blue screen of death at least once a day, sometimes twice.
Resistance is futile.
