Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
Stan is trying to update his computer, but he can't download the files (there's an exclamation point). So he turned it off and turned it back on and it updated anyway. Leo says that it's likely his computer was made compatible by Microsoft and when he turned it back on, it did the update because it was ready to. Windows also has a troubleshooter that could help.
Ed created a PDF document, but it's been updated and he can't access it because the software is costly now. Leo says the best way to protect his documents is by using "Print to PDF." Adobe Reader is free. Microsoft has a PDF printer that's also free.
Steve has an old Gateway computer and wants to know if he can update to the latest Windows 10 Fall Creators update. It won't install, failing at 84%. It can restore the previous version, but he doesn't know why he can't update. Leo says that it should since Microsoft has opened it up to all computers now. But if he hasn't applied all the previous hotfixes, it may fail.
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.
Brian tried to rename a file and ended up renaming hundreds of them. How can he undo that? Leo says it's a common issue, and if he accidentally hit an asterisk while typing (which is on the 8 key), it could rename everything pretty easily. The good news is that it assigned a number to each duplicate name, so it doesn't overwrite the file. Brian just needs to figure out which file is which. There's an easy fix. Fortunately, Brian uses Carbonite, so he can just restore his backup.

Rene is having trouble updating Windows. It stalls out at 80%. He then reboots and it goes back to before he tried updating. Then he gets a blue screen and he can't restore or update. Leo says that not an unusual problem. If you think about it, with millions of computers, there's going to be a certain percentage that will experience issues like this, and updating while a computer is running is nontrivial. It could be something is blocking it, like a third-party antivirus app. It could also just be a bad download. Or this could be the Intel Spectre/Meltdown fix that is causing problems.
Don is having issues with Malwarebytes. Leo says that if he's experiencing issues with Malwarebytes, there's a good chance that he's been infected. The first thing a malware creator will do is disable online security software and prevent access to those sites in the browser. That's one of the reasons why Leo doesn't like third party antivirus apps. Leo recommends using Microsoft Security Essentials/Windows Defender.
David bought a refurbished computer from Best Buy. It turned off when the battery died, and when he turned it back on, Windows wanted to do a repair. When it did that, it started wiping out his entire Windows 10 operating system. Now he's stuck on the blue screen of death and he's worried that his version of Windows 10 won't activate if he reinstalls it. Leo says it will, but before he installs anything, he should get the data from it. If it crashed once, the drive could be ready to fail.
Philip says that after a Windows 10 update, two of his HP laptops won't let him view multiple tabs anymore. It's all full screen. The only way to go back and forth is to click on a "task view" button and select a smaller window to "activate." Leo says there are gesture controls that nobody knows about in Windows 10 and chances are good that Philip accidentally activated "tablet mode." In the lower right-hand corner, there's a quote box.
Richard wants to know if he can run Windows off a thumb drive for security. Leo says that's a smart idea and it's not uncommon for Linux users. He should just understand that it will be slower. But it will enable him to simply reboot if something goes wrong. Leo recommends using a disk imaging command to make a disk image onto his thumb drive and then he can just blast it back on when it goes wrong. He can even make it bootable.
