Windows Birth

Windows/Vanura Birth was an OS made by Oggosoft.

It was discovered in 2471 when the advancement of Earth managed to time travel thru a bubble and found a planet called "Inicium Novae" and they discovered the OS date, but didn't manage to find the End Of Support Date!

They got it right now.

FUN FACT: It's named Birth because at that date, the universe was formed.
