In fact, that's an extra upgrade that essentially was skewed towards folks using assistive technologies, but should work regardless of Windows 8.1 version, with this offered past the original update which ended in July of 2016.
The offer was always intended for people with various disabilities who are unable to use their PC in a conventional manner.
If you use assistive technologies, you can upgrade to Windows 10 at no cost as Microsoft continues our efforts to improve the Windows 10 experience for people who use these technologies. As it turns out, Microsoft has held open the upgrade window a bit longer, until January 16.
Microsoft chose to extend the free installation of Windows 10 from December 31, 2017, to January 16, 2018, in an act of goodwill, giving a time extension of over 2 weeks. It's still possible that it will get pushed back again, though this late in the game, it's best to assume today is the last day.
Quite recently on January 9, 2018, Microsoft officially declared its Windows 8.1 operating system as outdated and obsolete, and that it would not be updated with any new features. Windows 8/8.1 stands at around 12 percent.
Can we say for certain whether January 16 is the absolute, drop-dead, pinky-swear, final cutoff for the assistive upgrade?
Microsoft has allowed Windows 7 and 8.1 users to upgrade to Windows 10 for free via an "accessibility loophole". It's also possible that Microsoft's moment of mercy will end soon. But Windows 10 is far superior, and if you haven't made the jump yet, you should probably do so today.
Even though it is out of mainstream support, Windows 7 still remains one of the world's most popular computer operating systems, boasting a market share of around 40 per cent.
