We have seen vulnerabilities like WannaCry, Petya, Spectre, Meltdown etc. (please update me with the recent most severe vulnerabilities for Windows you know).
What I want to point out is, we need to have report individually or for all, that Which device is still vulnerable and apply the fix, either it could be Windows 7 or 8 or 8.1 or 10. And again get report if all are patched or fixed or did workaround to solve problem.
Appreciate your help!
