Dan is having issues networking multiple computers running different versions of Windows. Leo says that Dan may be having issues with HDCP. He should name each machine, and he should try it without his Windows XP machine.
Chester is using Windows XP on his old computer. Can he put Windows 10 on it? Leo says you may be able to, but you can definitely run Linux on it. Look at Ubuntu. But have it run off an external drive to see if it'll work. Then if it does, you can install it. And Linux has a list of others specifically designed for older computers - https://www.linux.com/learn/intro-to-linux/2017/10/4-best-linux-distros-....
John has an old PC that runs XP and he's going to install Debian Linux on it. He wants to keep XP on it to run dual boot, though. Can he still get Service Pack 3 to get it up to date? Leo says that Microsoft has killed XP development, so he can't really get ahold of it except through a third party archival service. He'll have to decide if that's legit. If he installs Linux first, it may prevent installing Windows XP in the process.
Victor would like to update Windows XP. Jason says that XP updates are still available but are usually just on an exploit by exploit basis. He recommends getting all the updates he can and install them. But after that, he should seriously consider not using that XP machine online because it won't be regularly updated.

Mary has an old XP computer and she's worried about getting the WannaCry virus. Can she get a patch to protect herself? Leo says that Microsoft has ended life for Windows XP, but did make a patch for it and she can go into Updates and get it. But according to Leo, 98% of infected computers with WannaCry are Windows 7 computers. So XP isn't even on the radar. It doesn't hurt to be safe, though.
Last weekend, the WannaCry Ransomware bit several hundred thousand computer systems, including sixteen hospitals in the UK. The ransomware infected the systems and encrypted all data. The reason this one was really bad is that it was a "worm," or a "network aware virus" that would spread out over the local area network to find other computers to infect, and bring the whole establishment to its knees.
Satbeer is an accountant and he uses some old programs sometimes. On his Windows 7 Ultimate system, he can still use XP mode. Is that secure? Leo says yes, because Windows 7 is still handling the backend while XP is virtual.
David has an old PC and he needs to get Windows XP for it. Can he still buy it? Leo says not in regular stores. He could find it on eBay, but he would need to make sure it's an official copy of XP. He'll have to be sure it has a hologram on it, serial number, etc.
Bernie has a laptop running Windows XP and use it to run software needed for his shop. He is worried because Microsoft has stopped supporting Windows XP and its respecting software. Leo says that XP isn't being updated either and if you have to be online, not having Windows Defender and Security Essentials is the least of your problems. There currently no new malware for Windows XP but the safest course of action would be to stay off line on that machine completely. The best option is to run Windows XP in Virtual Machine on a more recent laptop running newer versions of Windows.
Drew would like to know where he can download older versions of Windows. He has an old laptop that he upgraded to Windows 10. He's installed VirtualBox onto it so he can run an older version of Windows as well, but he can't find his old Windows CDs anywhere. Leo says that Microsoft offers older versions to developers if he gets a subscription, but it's not cheap.
