A Twitter user posted a tip that showed Windows 9 might not have been released, but it’s not forgotten. It actually shows up in Windows 11.

Why Windows 9 Was Not Released

There was a Windows 9, but it didn’t publish, while Microsoft released Windows 10 instead. It was previously codenamed “Threshold.”

When Windows 10 was announced in September 2014, a journalist who often writes about Microsoft wrote that Windows 10 was released instead of 9 because Microsoft “wanted to signify that the coming Windows release would be the last ‘major’ Windows update. Going forward, Microsoft is planning to make regular, smaller updates to the Windows 10 codebase than pushing out new major updates.”

There were other possible explanations suggested, such as 9 was an unlucky number, that it doesn’t sound as good as 10, and that Windows 8.1 was intended to be called 9. But that early notion was confirmed to be true.

Interestingly, Microsoft isn’t the only one to skip a version 9. the iPhone when from iPhone 7 to iPhone 8, but the same day iPhone 8 was announced, iPhone X was released as well. This was not “ex” but “10” and was the 10th anniversary of the iPhone. Apple simply wanted to celebrate the big occasion, so it skipped the iPhone 9.
