"Windows XP computers were mostly immune to WannaCry"

Much of the early focus on Windows XP was the result of the UK’s National Health Service, one of the earliest and most damaging WannaCry victims. A number of outlets blamed the NHS infections on computers running Windows XP, leading to widespread concern over Microsoft’s failure to release a patch. The NHS itself vigorously denied the claim, saying fewer than 5 percent of the service’s computers ran Windows XP at the time of the attack. In light of the latest Kryptos research, it’s plausible that unpatched Windows 7 systems were more of an issue for NHS.

In the days after the attack, Microsoft drew significant criticism for its failure to issue a public patch to protect Windows XP against WannaCry.
