As you can see here, the entire OS is just a Windows XP clone designed to look like it. It also interestingly enough has:
- no “iptables” service
- no spying (no noticed ones)
- access to / (system)
- no wallpapers
- less applications
The other OS was Red Star 3.0, this is 2.0.
Most of these UI components are mirrored or cloned directly from XP since Korea uses XP too in their computing.
