200,000 Windows PCs in the US among the 600,000 total worldwide. Are there really that many Windows PCs still running vulnerable old OS versions, or were they zero-days in more modern OS versions? These articles never say much about the details.
Win10 69.46%
Win11 26.74%
Win7 2.42%
Win8.1 0.72%
Win8 0.35%
WinXP 0.18%
If we estimate one Windows computer per person in the USA on average (~ 331.9 mil.), this means that more than 12 mil. computers run an unsupported Windows OS. (Or use your own estimate.)
