Celerity Technical Expert Simon Rose expands on the WannaCry ransomware and how it affects Windows 7.
A tweet released by Kaspersky Labs revealed that over 98% of all documented WannaCry infections were running versions of the Windows 7 operating system. At first it was thought old, unsupported versions of Windows XP were most at risk, but that is not true. One reason Windows XP does not show up higher is because the WannaCry would only run reliably on Windows 7 and would error on Windows XP.
Despite Windows 7 being released in 2009, it is still used on 48.5% of PCs - much higher than Windows 8.1 and 10 which are newer versions.
What this statistic does show is how important regular patching and updating is in keeping you (and your organisation) protected. It is more important than just running a recent OS.
