Why Windows skipped 9

Sehr schöne und logische Erklärung auf Reddit dafür, warum Microsoft die Versionsnummer 9 von Windows übersprungen hat:

Microsoft dev here, the internal rumours are that early testing revealed just how many third party products that had code of the form

if(version.StartsWith("Windows 9"))
{ /* 95 and 98 */
} else {

and that this was the pragmatic solution to avoid that.
