Lots of folks (from their perspective) with a genuine need to keep running on Windows XP suffered a lot of grief in Tech forums as being one of the root causes of giving WannaCry a platform to spread and thrive from, yet now it appears all the criticism may have been a little premature and unjustified.
For the record, I personally don't condone anyone using unsupported operating systems and actively encourage everyone I deal with to get themselves up to date, but I am also sympathetic to those who feel they have a genuine need to do that, so also think they shouldn't be condemned so quickly as being the root cause of allowing malicious software to spread.
These folks still need our expertise and support and should be given it wherever possible imo, including advising them of alternate cost effective ways they might be able to continue running their proprietary hardware or software solutions that may not readily run on later Windows version releases. I also applaud Microsoft for not taking the high road and issuing a critical patch in cases like this.
Windows 10 did a forced update. All my Chrome browser tabs were gone when I opened Chrome; I had tabs I really needed open to use today. On a hunch, I pressed CTRL+SHIFT+T on my keyboard and brought them all back. That was awesome.
