Almost All WannaCry Victims Were Running Windows 7 (theverge.com)

An anonymous reader quotes a report from The Verge: According to data released today by Kaspersky Lab, roughly 98 percent of the computers affected by the ransomware were running some version of Windows 7, with less than one in a thousand running Windows XP. 2008 R2 Server clients were also hit hard, making up just over 1 percent of infections. Windows 7 is still by far the most common version of Windows, running on roughly four times as many computers as Windows 10 worldwide. Since more recent versions of Windows aren't vulnerable to WannaCry, it makes sense that most of the infections would hit computers running 7. Still, the stark disparity emphasizes how small of a role Windows XP seems to have played in spreading the infection, despite early concerns about the outdated operating system. The new figures also bear on the debate over Microsoft's patching practices, which generated significant criticism in the wake of the attack. Microsoft had released a public patch for Windows 7 months before the attack, but the patch for Windows XP was only released as an emergency measure after the worst of the damage had been done. The patch was available earlier to paying Custom Support customers, but most XP users were left vulnerable, each unpatched computer a potential vector to spread the ransomware further. Still, Kaspersky's figures suggest that unpatched XP devices played a relatively small role in the spread of the ransomware.

    Really old systems in Hospitals that only run winblows XP and were effecting the lives of patents were the main concerns on the XP front. Only a few getting infected with wcry and encrypting critical patent files can seriously effect how Medical Facilities are functioning. I don't doubt that Win 7 got hit hardest. When it gets behind the weak hospital firewall and starts killing that shit, XP boxes didn't have the available patch to stave it off.

      Microsoft broke Windows Update on Windows 7 soon after the Windows 10 Upgrade windows closed with some botched updates.
      Windows 7 computers that didn't take the update were treated with a runaway svchost.exe processes that consumed 100% of a core and near a GB of RAM while halting future updates at the same time. The only way to get performance back was to disable Windows Update. Even reloading Windows 7 from scratch didn't solve the problem. Updates would never come, and svchost.exe was stuck at 100% and massive amounts of memory. Microsoft let this problem linger for months probably in the hopes that users would upgrade to 10. Others here have suggested that it was due to MS not releasing roll-up updates and letting the library grow beyond what Windows Update was able to process.

      I realize though that having a zillion combination of patches might be a pain to support, so here's what I'd like to have seen:
      1. Microsoft releases version A. You can either stay on stable branch A or get rolling updates A*.
      2. After 4 years Microsoft takes the current setup, calls it B. You now have three supported configurations A, B, B*.
      3. After 8 years Microsoft takes the current setup, calls it C. You now have four supported configurations A, B, C and C*.
      4. After 10 years support for A ends, before that you should migrate to B, C or C*.
      From there they'd just bounce between 3-4 supported configurations of N-2, N-1, N and N*.

      Most importantly still regardless of when it's updated everything should come with an off switch. I don't mind if Microsoft asks for telemetry. I have a problem with Microsoft demanding telemetry. It's like my car dealer refusing to service the car unless I've kept a log of how I've used it. I could almost live with that if you had to find some obscure setting only 0.01% would turn off. But it's when you deny me that choice this smells really foul.
