So, is Cliff S post #85 correct?
I am assuming if we go buy that
July 29, 2015 Start of Mainstreet support
July 29, 2020 End of Mainstream support Unless a service pack extends it or Microsoft does.
July 29, 2025 End of Extended Support Unless a service pack extends it or Microsoft does.
Then comes the new questions, what happens you your Windows 10 computer when extended support ends for example you can't upgrade do to hardware or choose not to pay for an upgrade? Will the computer still work or will you be locked out?
. . .he made do it. . .
I told Alpha that, that was the old model(you'll see what I mean if you follow the link), but I suspect the "principle" is the same. But any future "Upgrades" will probably be given, if you are still using the same PC(will your system support them will be the question). A good example is DX12 doesn't do anything for me, my PC(graphic doesn't support it, also I could not use a Hololens, but if they improve Cortana or give Edge a new function we will get it if it comes out in 20 years. When a company talks business legalese and say supported life time they are also talking planned obsolescence.
One time I had redhat, opensuse, Lubuntu, Fedora, windows 7 all on my system at the same time. I found out that Linux desktops options were the same across distros. I have tried more Linux disto that what I have mentioned.
I think it's not likely correct that as Windows 10 ages, that original builds will still be supported in perpetuity though. If you install Windows 10 this August on a DuoCore machine with 16 GB, that machine would receive updates and build improvements as long as that hardware supported it.
But sooner or later, let's say in 2019, a new Windows 10 build will arrive that absolutely requires a quad core CPU. So those of you who started off on a quad core? Great! You just continue along. I would suggest that the obsolete DuoCore user would be in a similar situation as a Windows 8.0 user is right now. You'll get security updates for a another year or so (maybe the extended time will be lengthened), but at some point you'll be urged to move to a compatible machine that can handle the newest generation of Windows 10.
I would really look at the MacOS X model as a guide.
