Here's how to get Window 10 for free -- still
Found on CNet News on Monday, 01 August 2016

You qualify for the free upgrade if you use assistive technologies, which include such features as a magnifier to better see the screen, a narrator to read text aloud, keyboard shortcuts and an on-screen keyboard.
Microsoft has not announced a deadline for the free offer for users of assistive technologies, so those of you who still want Windows 10 should grab the freebie while it lasts.
10 has failed expectations and people do not want to upgrade unless forced. Prolonging the deadline won't magically increase the marketshare; Microsoft is simply headed into the entirely wrong direction.
