Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
Jeff has had Windows 10 for a few years and suddenly he's getting a demand to activate again. Leo says that is a known problem with Windows. It's an erroneous notification cause by an error on the authentication servers. Microsoft is in the process of fixing the error, and he'll likely get a fix on Patch Tuesday.
Dale bought a Windows 10 DVD upgrade disc because he couldn't download it. Leo says he should be able to download it by pressing the Windows Key + "Update and Security." Then he can enter the new Windows 10 Pro product key, press "next", and it should download for him.
Fred is legally blind, but he knows of a new app by Microsoft called Seeing AI. It offers text reading, barcode scanning, it will tell you if your light is on. It basically narrates the world around you. Currently only available, quite ironically, on all Apple devices.
Leo says another option is called Be My Eyes. It works on Android.
Gary downloaded Linux and it seems to be stuck in the BIOS. He can't download Windows Update. Leo says that he can download multiple operating systems, but Windows can run into trouble when trying to dual boot from the GRUB Boot Manager. When uninstalling Linux, he may have run into issues of missing Grub boot features.
Brett just updated to OSX Mojave and hangs up on the login screen. Leo says clearing the PRAM or parameter ram can sometimes solve issues like this. Also, reboot with CMD R and that will enable you to reinstall the OS. Maybe it wasn't updated properly. If that doesn't work, Leo recommends making an appointment at the Genius Bar in the Apple Store.
Chatroom says to boot into safe mode, press and hold the shift key, and it will install the absolute minimum. If it works OK after that, then there's an app that isn't compatible that's hanging things up.
Ron is having issues with Thunderbird after a recent security change that is causing him issues. Leo says that Thunderbird has largely been abandoned by developers, who are simply not keeping it up. He may want to check his IMAP and SMTP addresses to make sure they are configured correctly. He should double check how to properly log into it, and what port he'll need to use. His ISP can help him with that.
Steve's Windows 10 machine won't update beyond 1803. Leo says that Microsoft pulled 1809 because of some bugs. It will be fixed and available again soon, though. Feature updates aren't critical — it's just the security updates that are important. But if it's preventing him from getting security updates, then it could mean the update is blocked and he'll have to clear 1803 in order to get back to updating. Microsoft has a troubleshooter for blocked updates, and Leo recommends running it.
Joseph has the Windows 1809 update and he did a clean install when doing it. He's had no problems. He wants to know if he can get Windows from a third party with an HeiDoc ISO downloader. Leo says that's a bad idea. Microsoft offers its own ISO download through the Media Creation Tool. That's really the safest way to get it.
Lee loves to buy refurbished computers and install Linux dual booted with Windows 10 on them. Is there a version that looks like Mac? Leo says he usually recommends Elementary OS, but there's another one called ELive. Lee should check out DistroWatch.org. There's hundreds of versions of Linux there that he can check out.
Thomas was running into problems with Windows Defender blocking Camtasia and OBS from saving files. Leo thought that if he had been running as a limited or standard user, that he simply wouldn't have the permissions for that, but he's running as administrator. Leo says this does seem suspicious. Thomas should set up a shortcut for Camtasia and OBS to run as administrator. When you right click on an application, one of the options that comes up is "run as administrator." It may be that those apps need more permissions.
