A downloadable operating system for Windows

Surplus OS is many things depending on the story you listen to, the most impressive of which, is fiction. This story describes Surplus OS as an operating system created by Techmore Corp. on Friday, May 15th, 2015 for their own specific PC-based computer platform. This platform was modeled after vintage hardware of the 1990's, similar in spec. to long since unsupported Microsoft Windows™ 95 and 98 systems. This is about where the made-up tale ends however, as even though third-party developers existed, the company couldn't stay afloat from the little profit the systems and software made. As a result, the decision to sell Surplus OS to us (the Shaggy39 Studio) was finalized during Surplus OS – Version 3's development, and before the company fizzled out.

The REAL story is that I made Surplus OS during my middle school days, as Batch (Windows Command Prompt scripts) was the first programming language I taught myself.
