"Microsoft officially ended their free Windows 10 upgrade program on July 29th. For those that did want to upgrade but didn't get around to it, there are still a couple of known ‘loopholes’ to get a free Windows 10 upgrade which Microsoft hasn’t bothered to close, even five months after the offer officially ended.
Microsoft is continuing to offer free Windows 10 upgrades to those who use assistive technologies, such as a screen narrator or magnifier. Anyone running Windows 7 or Windows 8.1 qualifies for the offer, as Microsoft isn't really checking to see whether you are actually using these assistive tools.
The upgrade process couldn’t be simpler. Just head to Microsoft's accessibility website, download the program that's listed on their upgrade page, and then install your free Windows 10 update."
