20 years ago today, Microsoft released Windows 95 into the world.
It followed up on the success of Windows 3.1 and radically expanded Microsoft's dominance in both the personal computing market and the enterprise world.
The OS included many features that have since become legacy hallmarks of Windows, like the Start menu and the taskbar.
It was a pivotal upgrade that introduced many, many more to computer interactions. Chances are, you have experience on or around or complaining about Windows 95.
But does it really need an anniversary? Probably not.
It's an important moment in technological history, but it doesn't really need a day when we can remember the launching of an OS.
HOWEVER, we do need a day when we can remember Bill Gates and former Microsoft CEO Steve Ballmer dancing at the launch.
Never, ever forget.
