Microsoft still has their upgrade plan in place for those that use assistive technology.
"According to the terms of the offer, you can only use this offer if you use “assistive technologies” on your computer. These include screen readers, magnifiers, and anything else that makes Windows easier to use. Microsoft isn’t checking whether you use assistive technologies or even spelling out a list of assistive technologies that will make you eligible for the offer, though. It’s the honor system."
So if you are like me, someone who that has to increase font size, well you are using assistive technology. Here is the link.
