It is remarkable that Windows 7 is reaching end of support on January 14 2020 while maintaining something approaching 27 per cent market share among Windows users, according to Statcounter.
This is down from 35 per cent in December 2018 but still substantial. Windows has a share among desktop users of around 77 per cent, so that is around 20 per cent of active desktop PCs.
