      One "security tip" put out last friday was to add external SMB access to the blocked port/protocol list on on your router settings.
      Not sure if this is pertinent but I did it anyway as it was an obvious security hole on my router. My only PC uses windows 10 which apparently wasn't targetted in the initial attack.

      What has been said throughout this issue is that you should install the latest security updates. It's also been suggested that keeping your AV software up to date is also a good idea.

      There have been instances in the past where a Windows update has actually messed with computers. In one specific instance I'm thinking of where an update messed up a number of computers, the roll-out was halted and a revised update was issued days later.

      AV software does slow down your computer. By it's nature it's making your computer work a little harder. I've heard complaints in the past about this. Unfortunately by it's very nature the AV is working in the background and takes a little processing power, memory and uses the hard drive as it checks all those files you are loading.

      NoScript is a blinkin' good idea too, if you can bear everything being broken. Surprising how much crap tries to run even on bland pages.

      What many peope seem to forget is that a lot of the machinery used by the NHS uses XP code and needs to interface to XP. Until the software in those machines is changed XP based code will still be around, so it is not JUST the NHS that needs to get up to date.
      I would like to bet that there is an absolutely huge number of devices around that use XP code internally.
      I know my washing machine, TV, book reader, fridge, oven, intelligent light bulb do just without really thinking.

      And there is only ONE of those that I can add security to.

      Would that be the washing machine?

      Curiously I HAVE been offered an uprade to the software in that. They wanted me to change it to be able to remotely control it - but being as it is a very old and reliable machine I told them I would wait until it dies. My son has gone through three machines since he got married, and we bought it long before then.

      I guess that highlights the fact that many devices will use XP code internally, but since they aren't connected to the outside world, there isn't an issue.

      As for the ageing kit in the NHS that requires a PC to run XP, that doesn't surprise me.

      Whilst at college we had a trip to one of BT's sites and toured their computer department. Whilst some was relatively new, much of it was dated. Their plan was to gradually update pieces over time so that items which were 30+ years old were replaced before the 10 year old or 20 year old kit. This way they always had something able to do the required tasks.

      Medical kit tends to demand a huge premium due to it's function to improve lives. Occasionally things have gone wrong in the past and the work that hopefully prevents such repetition will cost in terms of research and development time. This, along with speciality and litigation costs, ensures that the makers of medical kit can charge a high price.

      I seem to recall that the makers of scalpels, as an example, are very specialist. No one has been able to replicate the process successfully.

      So basically I wouldn't be surprised if there were kit out there running Fortran, COBOL, Pascal and machine code, let alone XP.

      Once more the danger isn't so much that they are running an old OS. The danger comes from external access.

      And for all the XP bashing, it seems that W7 was worst affected!

      Well that is hardly surprising since there are far more of them.
      Don't forget that in both cases patches were available BEFORE hand if people bothered to keep the patches up to date.

      Forget leaves on the line. I was once stuck in a Southern Rail Electrostar train which appeared to have broken down. The driver switched everything off and rebooted the train (which I believe was running Windows XP) before we were able to proceed on our journey. I know that the train had GSM radio but don't know whether the train's controller was connected to a wider network.
