Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
John is working on a Windows 7 computer that has trouble shutting down. It just keeps restarting. Leo says that's not unusual, especially for an older system like Windows 7. Chances are, the OS has never been reinstalled, and there's a lot of "kruft" that prevents an orderly shutdown (called "bitrot").
Mike reinstalled Windows 7, but it won't authenticate. He contacted Microsoft and they want him to buy Windows 10. Leo says that can happen when modifying a computer significantly to the point that Windows doesn't recognize it as the same computer. But Microsoft still supports Windows 7, and they can reassign his serial number to the new configuration, so that's odd. It may be that using reinstall disks that didn't come with his computer could be causing it.
Jim has a Windows 7 computer and about two months ago it started messing up his mouse, which freezes up anywhere from a few seconds up to 5 minutes. It usually happens after checking his email and then going online for a while. Then he exits out and the mouse freezes and he has to reboot. Leo says that there's probably something running in the background that's slowing down his computer and causing processes to back up. Leo suggests trying another browser, like Google Chrome.
Ted put Linux on an old Vista Machine, but when he went to use the app Turbo Tax online, it said that it wouldn't support Linux. Leo says to try the Chromium browser in Linux. It's more open source. But being a standard web app, it should work regardless. Is it secure? Leo says it is, but it's not 100% flawless. It does have the benefit of being obscure, though. Hackers want to go after the most people, and open source is such a small segment that it's relatively off their radar. Certainly more secure than Windows Vista.
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.
