When Microsoft rolled out Windows 10 back in 2015, the operating system was met with high praise despite the poor reception to Windows 8. Since then, the software has been made available for a free update for Windows users, and many have taken advantage.
The company stopped offering free upgrades to Windows 10 as of July 2016, but there was a loophole extension for users who requested a free upgrade due to the operating system's accessibility features. Microsoft has updated their website to state that all free Windows 10 upgrades will cease on December 31st.
For those buying a new PC, it is unlikely you'll run into any trouble with this dilemma in 2018 as nearly all computer manufacturers are shipping their new models running the latest OS. However, with only 29.3% of PC users running Windows 10 as of last month, the adoption has been slower than expected and those looking to upgrade at no cost should make an effort before the end of the year.
