Timely reminder that you can still get Windows 10 for free as an upgrade.
Microsoft ended their year long free Windows 10 upgrade program for consumer customers on 29 July 2016 just prior to the release of the Windows 10 Anniversary Update in early August.
There is however, one group of customers that still have access to that free Windows 10 upgrade. If someone is on Windows 7 or 8.1 and they use Assistive Technologies then the upgrade is still accessible.
Just click the Microsoft Official link - there is no check that you are using Assistive Technology, it's just a free upgrade.
