Perhaps all of those who said "Windows 10 is last Windows" should check actual Facts:I also recall as clear as day that Windows 10 would be the last Windows OS. We all know how that worked out.
If Windows 10 was supposed to be the last version of Windows, why is there a Windows 11? Well, because Windows 10 was never officially the last version of Windows.
So no, Microsoft never said Windows 10 is last Windows. That was just rumour that many websites called as fact.
This is basically same when Lisa Su told Ryzen 3000 series will have "Globalfoundries IO die" and then almost all hardware websites told that IO die is 14nm 🤦♂️
(It was actually 12nm, Lisa never told it was 14nm. Always check facts despite 100 sites telling same)
