This is going to send FAR fewer PCs to the landfill than them going EOL and yanking the free upgrades from Windows 7 and 8/8.1 to 10 is doing. Except for when you pile on the fact that a lot of the PCs that they GAVE free upgrades to 10 to that had valid 7 and 8/8.1 licenses have now had them revoked and they are not making any effort to resolve that problem. So basically EVERY single Windows 7, 8 and 8.1 machine, and a whole bunch of Windows 10 machines that were originally Windows 7 or 8, are also going to the landfill because Microsoft has made them worthless. They were still worth something to a lot of users because they COULD still be used for many years to come, just not necessarily as gaming systems but there are far more users out there who do not game than users who do, but now they can't be because the activation servers for 7 and 8 are gone and they can no longer be used with Windows 10, so worthless now. And then add the list of Windows 10 machines to it when the time comes.
It's ridiculous. Laws should be passed saying either you support these systems for a minimum of ten years, at least, and/or you do like with automobiles and tell them if they don't want to continue supporting those OSes after a certain point then at that point they open it up to the open source communities to offer continued support or the aftermarket, just like they do with automotive parts. Something. It's getting ridiculous for all these companies to sell you expensive hardware or devices, with the idea that you are going to have the use of that device for many years to come, and then a couple of years later decide "meh, we don't want to support it anymore so we're shutting it down" which ends up making the device completely worthless and forcing you to have to purchase some other newer one that they will do the same thing to in two years.
