Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
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-....
Janet is worried that she needs to clean up her system and have a separate antivirus system. Leo says no. You don't. You don't need a third party cleaner and you don't need a separate AVS app. Windows Defender is just fine and it comes with Windows 10 for free. But even the best AVS isn't going to protect you against your own online behavior.
Kevin is having issues with iTunes. It won't open at all. Leo says it should, and that isn't unusual. Sometimes .dll files get corrupted. Try uninstalling and reinstalling iTunes. Will that delete his music? Leo says no. It'll be safe. But Leo says that iTunes is an app that has never really worked well, and over time, it's gotten more ungainly and difficult to use. It really needs to be stripped down and built from the ground up. Alternatives include Double Twist. Media Monkey.
After having his computer replaced, Lloyd opened his Outlook, and now his email disappears or deletes when he tries to read them. What is going on? Leo suspects that the technician did a lousy job moving over his data and apps. Leo recommends to log into Gmail online and verify that your email is actually there. It's probably still there. Then, what Leo would do is reconfigure Outlook under account settings. Delete Gmail and then reconfigure it. You can google how to setup Outlook with Gmail. It's easy to redo it. There's also a repair Outlook option under Programs and Features.
Julian called in with a suggestion for for Larry in Prescott, AZ, who wanted to connect an external camera to his smartphone for use with an app called BeMyEyes that acts as a visual aid. Julian's idea is to either use an Android device for this, or to use a service called aira.io. This service works in conjunction with glasses that would be worn and identify what things it is seeing.
Calling Minecraft the "Lego" of the 21st century, Leo says that Microsoft has created an education edition of the game for computer programming, chemistry, and a host of other teaching tools within the game itself. It's also available on the iPad. Leo says it's a very cool idea and a great way to learn science, technology and math (STEM).
Patrick uses WhatsApp, but he's concerned about security on his phone. Leo says that the danger isn't that the app will be malicious. It's a safe app if he gets it from the Google Play or iOS App stores. But it is owned by Facebook, and they will use his data for advertising. It isn't using personal details, but some details such as search data, likes, and keywords.
Patrick is also worried that his old iPad isn't being updated anymore. Leo says that while he won't get the most recent iOS, the security updates will continue. Nothing to worry about there.
David just got the latest Windows 1803 update, and broke several of his apps. Is there a way he can roll back to use them? Leo says that he won't want to roll back. It's too important for the security. If it is the 1803 update, that's not as important as the security updates because it's a feature update. So he can roll it back if he wants and defer it for up to a year. Sooner or later, though, Microsoft is going to force that update upon him.
Robert is having an issue with UWA apps bought in the Windows Store. He can't connect using them. Microsoft has been dealing with this issue for three years, and he can read more about it at answers.microsoft.com here.
Maurice's Outlook contacts disappeared and now he can't send group emails. Leo says there could be a few things happening. Outlook's autocomplete is constantly looking at the contacts, and if it's missing, then it can't read them. If it's intact, then it should come out, including his group list. Carbonite will backup his data, but if the link between his contacts and the group list is broken, then that could be part of the problem. He should try and verify that his address book is there. If the address book is gone, then there is the problem. If the list is there, then he can back it up.
