Vanura -∞

Vanura -∞ was created by Oggosoft, The first-ever computer company in existence.

Info
Vanura is the very first OS in existence. It was released before the big bang in 13800000000BC.

Startup Screen
The startup screen is very dark, Oggosoft could only do images this dark around this time, so it makes sense why.

The image has been brightened so it's viewable, Original image is in the info box above.

Desktop
Since the boot screen is small, the desktop is small. As a result, it can only hold 12 icons at a time and they have to be smaller than the cursor. Unlike several Windows versions, there is a power button next to the start button. When clicked, the button opens up a menu, which has 3 choices: Shut Down, Restart, or Sleep.

Storage
The OS only takes up around 3 Kilobytes, and the storage is around 1 Kilobyte or more. Its use was very, very limited at that time.

(Yeah. it doesn't make sense but, does everything here exist and make any sense?)

Bugs
It has over 1 billion flaws in the computer itself, which is a very usual thing that happens for the first computer ever. Mostly, the unstable computer running this OS crashes after a couple of milliseconds after it boots up. The BSOD that shows up after the computer crashes only says “Unknown Error” without any error code or name being told.
