The messaging was so bad around this, that as an employee of the damn company, I was told 10 was the last version. It ended up that the original statement was made in error, it was never planned to be the last version. It took them I think 3 years to make an official internal statement to tell us to stop describing it as the last version.

Windows 10 was strange. It turns into rolling release since 2018 with Vibranium code base, and never get really upgraded after it.

I was a real thing. But then µ$lop changed it's mind
