It’s perfect for home computers. I only use it to write books and stay in touch with family.
They just don’t want to supply any support or updating for Win7.
I'm certain that if they could have cut off the security updates before Jan 2020, they would have done so already, and then explained that Win7 is no longer secure because the security updates aren't there.
See how it all makes sense? /s
The real reason behind this cr@p is that Win10 conversions have stalled since the "Free Upgrade" offer went away. They're increasing market share by the sales of new Win10-pre-loaded machines, of course. But businesses are slow to convert and for most of them, there's nothing in Win10's features to offset the substantial cost of converting an organization to Win10.
As a result, Microsoft's efforts to convince Windows users to convert to Win10 has, I'm very sad to say, turned the company into a F.U.D. spewing juggernaut. As one who has used, programmed for, and supported every Microsoft operating system release since 2.0, and who used MS-DOS since it first appeared, this is a HUGE disappointment. The company used to be much better than what they've become.
