On September 30, Microsoft announced the upcoming release of the latest version of its operating system,
Windows 10. The strange thing is that there was no Windows 9. They went straight from version 8 to 10. It's been noted that this makes real an April Fool's Day hoax published by InfoWorld in 2013, which claimed that
"Microsoft skips 'too good' Windows 9, jumps to Windows 10." Microsoft hasn't explained why they really did decide to skip version 9.

When first reported this was believed to be an hoax, but some searches on public code repositories apprently confirmed that it is a real problem (if this alone was sufficient to motivate MS to change the version or if there're other reasons is another thing).
