Vanura -∞

Vanura -∞ was created by Oggosoft (the first computer company in existence). There are 7 updates, Update 0, Update 1, Update 2, Update 3 and so on until 7, which 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 and 9 were never released unfortunately.

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 of how hard the number of 13800000000BC is to enter, there's a 1-bit coding, and that is the strongest thing a computer was able to 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 info-box above.

The prototype would have the text be white but every update makes it darker. The image below the lightened image is Update 0

It was preceded by an unknown operating system, most likely none and succeeded by Vanura Birth.

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 2 KB, in which the storage is around 1 Kilobyte or more. Its use was extremely limited at that time.

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

Update 0 was only 1 KB instead of 2

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...

Gear
Before they introduced the mouse, a stone, which had a pressure plate inside, was used.

To click, destroy the stone.

And to move the Cursor, you launched it out of the multiverse to move it 1 nanometer, though it was revolutionary at the time because you can control something!

Actually, an ancient mouse, which has a ball under it that controls the cursor, is used for this OS. There is a button on top of the mouse. To left-click, press the button. To right-click, press the button 3 times in a row. And for the keyboard, the keys were positioned in ABCDE format instead of QWERTY format. These make navigating and typing on the OS cumbersome, though it was revolutionary at the time because again, you can control something. However, you could use the QWERTY keyboard with this OS along with the modern mouse that has 2 buttons and a rolling wheel between them. However, right-clicking or rolling the wheel on the mouse does not work on Vanura -∞, as there are no scripts for the OS to make them function. However, the scripts that control the RMB and the mouse wheel can be added to Vanura -∞, making it easier to navigate the OS.
