OSModgen X is a OS made in Early 2016 as a experimental OS, you weren't forced to use it so some people still used OSModgen Saturn at that time because of it still been updated. This style was called "Simple Design", it is similar to the metro style & the other flat designs from that time, but it had more personality than most of the flat design made by other companies, having gloss and gradients for the icons.
Note: This is NOT the first time the password thing was added to non-office OSModgen systems but it may be one of the first ones to use it by default. Fun Fact: A OSModgen X based OS for low-end computers/laptops was released 1 year later in 2017, it was called:"OSModgen Nano".
