Charles uses a lot of Explorer windows, and every time he pulls a USB device out, his entire file tree collapses. Leo would look for a way to create an Explorer window that is rooted to a specific directory, so it starts at that directory. Windows now has a "Quick Access" section in the Explorer window, and he could put folders there. This would be more of a workaround, though.
Bob's friend has a computer who's Windows 7 update is taking forever to install. Leo says that Microsoft has patched it seven times to try and and speed it up and in 2016 they finally fixed the issue. Chances are, an update failed and that's what caused the logjam. It also could be malware that disabled the update utility without his knowledge. Leo recommends clearing all the updates and starting over.
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.
Jane has been told to clean up and defrag her desktop every week. Is that correct? Leo says no. It's not necessary to defrag anymore as modern operating systems take care of this on their own. Additionally, for solid state drives, defragmenting is meaningless. Jane also doesn't need to use "CCleaner" to clean up her registry either. In fact, she could make things worse by trying to clean her registry. Sure, she can delete temporary files and clear caches, but all that stuff can be done directly in Windows.
Bernie has an old PC that he put Windows XP on. How can he still get the service pack updates? Leo says he can get them directly from Microsoft. He can get right up to April 2015. After that, Microsoft stopped Windows XP development. He won't be able to get anymore patches after that date.
Mike got an error message that something had stopped working when he installed DropBox. He uninstalled it, but the error is still popping up. Leo says it sounds like the uninstall didn't get rid of all the necessary files and so the Windows registry keeps referring to them. He should go to DropBox and see if they have a removal tool. He can check his services in Task Manager too. That will tell him what it is and he can at least disable it.
Mike wants to know how to tell a real email from a phishing email. Leo says to hover over any link that would send him to a website, and see if the link is legitimate. He should never click on it. If it says to install something, or even asks for a credit card, don't do it. That's usually the first sign of an intent to do something nefarious.
Jeff is having speed issues on the internet with his Linux machine. How can he check for speed? Leo says that Linux has built in utilities just for this purpose. How about something that's cross platform with Windows? Leo says that is a different issue. He can run SpeedTest.net but that will only give him the speed of his internet connection, not his computer.
Ken has an Acer laptop running Windows 7 and it was acting up so he slapped it, and now it only works in safe mode. Leo says it clearly something shook loose. Don't beat your PC!
Sue got a new Alienware computer that has been maxed out in memory. She uses it for CAD. She transferred all her data and settings with Laplink PC Mover. Leo says that is an ancient way to do it. Sue says now it has something called Commodo Internet Security on it now. Leo says that is a horrible program and she should get rid of it immediately. BleepingComputer.com has instructions on how to do that.
