Operating system mockups

Operating System Mockups (OS Mockups, OSM) is a term for fictional OS, or versions of already existing OS. It might be Windows, Linux, Sviger, Cluster, LavaOS, ReviveOS or any other OS. It is Windows Never Released and Never Released Operating Systems combined.

It is unknown exactly who started the cult, although the first person to create a video under OS Mockups was Neptune98. However, this video was scrapped and later replaced with a WNR due to Nept losing interest and time. Other people would go on to create OS Mockups videos, along with OS Mockup Compilations/Collections.

There is a kit to produce OS mockups known as The OS Mockups Kit. It is split into four parts, and contains many graphics and sounds from different OSs, though it still has a focus on Windows.
