> Whatever happened to the goal of Windows 10 being the last version of Windows
That was never intended to actually be true. They said that because IT people with actual discernment were looking at Windows Ten and going "Eh, this version is pants, I think we're gonna stick with Seven for now and see if Microsoft can get their act together for the *next* release." And that would be a disaster, because then they (and more importantly their companies) might not pay Microsoft any money for upgrade licenses for Ten.
Once just about everyone who ever pays for software upgrades let go of Seven and upgraded, the "Ten is the last version" line was promptly dropped, because it was no longer needed.
There is one significant way in which Eleven is better than Ten: the "is your PC ready for the upgrade" check is significantly more realistic about system requirements. Ten will happily install on a system with 8 GB of RAM, which is less than a quarter of what is needed to run it at an even vaguely acceptable level of performance, and it doesn't even *warn* you that there might be a problem. The result, is that the system can't be used for anything because it's too busy swapping, because the core of the OS doesn't fit in physical RAM, let alone any applications (and the Eight/Ten/Eleven virtual memory subsystem is even more pants than the NT/XP/Vista/Seven one). Eleven doesn't have this problem: it actually tells you your PC isn't good enough.
I still say Seven is the best operating system Microsoft has ever produced. I wouldn't be terribly surprised if it ends up being the best one Microsoft *will* ever produce.
