Fean's WNR kit

Fean's WNR Kit is a Windows Never Released content pack made by fean and the predecessor to the OS Mockup Kit. It was made in 2016-2017, and was commonly used by WNR creators throughout that time.

A modified version with more resources and premade PSD files (specially real versions remakes) was made by Nermal Cat in 2017, used by WNRers too.

Before Fean's WNR kit
Before 2016, there were not too much resources/assets to make OSM, the WNR makers had to search official resources in the internet and make their own assets; however, when MinderiaYouTuber released the third update of his Windows with Never Released Versions series in June 2016, he released the first version of "Windows Never Released Fan Fiction", a pack with the premade PNG bootscreens in the original resolution showcased in WHwnRV Update 3 and with fanmade and official Windows logos, it was not intended to be editable, but it was used by many WNR makers during mid-2016 editing the premade bootscreens.

Then when Minderia released WHwNRV Update 4 in August 2016, Minderia released a new pack called "Windows Never Released Layers", intended to be used to create WNR screens instead of just downloading premade ones, including PNG layers, fonts and logos; it was popular during mid/late-2016 until 2017, when pre-U5/U5 was released.
