Vanura -∞

Vanura -∞ was created by Oggosoft, The first-ever computer company in existence. There are 7 updates, Update 0, Update 1, Update 2, Update 3, Update 4, Update 5, Update 6 but 7 was being worked on until Myhsja died, Thomas was the only other person in the company, so he continued working on Update 7, Update 8 was never released, however. Update 9, I guess...

Building The OS
Vanura is the very first OS in existence. It was released before the big bang in 13800000000BC. Although it was most commonly known as -∞ year because it is too long to go to this year... There's a 1-bit coding, and that is the strongest thing a computer can handle in -∞

Boot 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 infobox above.

The prototype would have the text be white but as it updates. It gets darker... The image below the lightened image is Update 0

It was preceded by an unknown operating system and succeeded by Vanura 1 Centilon BC

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 2 choices: Shut Down or Restart.

And the desktop below the bright image is the Update 0-5 Desktop...

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?)

And also in Update 0, it is 1 kilobyte...

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. But the Update 0-4 doesn't have a BSOD, so the Update 5 is shown...
