Re: what happens next?
Regardless of what they said, or the context it was said: Windows 10 was the last version of Windows that *I* did buy.
And that does not mean sailing the high seas. I began to think I might discontinue my Windows experience when I saw Windows 8 at work, I decided to opt out of that version.
I used Windows 10 dual boot for about a year before being confident that it has nothing to offer me anymore. I have that as a vanilla install which gets entirely unused and is mostly forgotten about - waste of an good SSD really.
