Windows 7 has officially reached the end of support, so users running it have three options to choose from: stick with Windows 7 and face the obvious security risks, upgrade to newer Windows, or migrate to a non-Windows platform. As far as the last option goes, Linux distro makers know how big this opportunity really is, so they started poaching Windows 7 users in an attempt to increase their install base.
After Canonical tried to lure Windows 7 users to install Ubuntu, a number of Korean companies developing their own custom Linux distros have launched similar campaigns specifically supposed to convince Microsoft customers to make the switch.
