Bill has been getting DLL errors. Leo says that the only real way to solve this is to do a complete Windows reset, which is really easy in Windows 10. Bill can just press the Start button, then select Settings > Update & Security > Recovery. Under "Reset this PC", he should select "Get Started".
Steve forgot the password on his all-in-one Windows 10 machine. Leo says that can be a serious problem in Windows 10. But since Steve used his Microsoft account to log in, he can change the Microsoft password and he should be able to make it work. Microsoft also has a utility called MSDaRT, which has a feature called Locksmith Wizard that will reset his Windows 10 password. Third party utilities include PC Unlocker.
Jim says that every time he does a Windows update, something goes wrong. It always deletes the restore point after updating, too. Leo says that Windows is deleting the restore point because he doesn't have room for a second one. Freeing up space on the drive could help. Leo doesn't trust restore points though, anyway. They don't work very well.
Sarah is worried she may have malware on her system. She ran malware bytes and it says she has 170 possible malware issues. Leo says that probably isn't the case. Malware Bytes will give false positives, or overreact to things in the browser it doesn't like. Malware Bytes can also slow the computer down. What really probably happened is that her browser simply crashed. Leo suspects that Sarah's hard drive is getting flaky, and is starting to fail. The good news is her computer is only a few months old and she can have it repaired under warranty.
Dave's Windows 10 upgrade failed and he had to revert back to Windows 7. It's ten years old and he can't sync his data from his tablet. Leo says it may not be modern enough to recognize the iPad. He'll need iTunes and it probably wants a more recent OS to run that. Windows 7 should be modern enough, though. Dave should back up his data, wipe the drive and reinstall Windows. Then update it, and try again. When he gets iTunes installed again, it should be able to sync. The benefit of reinstalling Windows is that it'll run faster.
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").
Todd's pro-level support with Dell expired right as his Wi-Fi stopped working. When he turns it on, it just keeps turning back off. Is it broken or is the software doing something? Leo says there is a function key on the keyboard that can turn off the Wi-Fi, and if it's sticking, that could be causing the problem. If it's a business laptop, it may also have a switch on the side that can turn it off. Driver issues may also be causing it, so he should go to Dell and download all the latest motherboard drivers.
Don has an HP machine running Windows 10 and it's having problems when it goes to sleep. Leo says that he should make sure "Hibernate" is disabled. That causes a lot of problems. It can also not wake up from regular sleep, and it's been a long-running problem in Windows that doesn't really have a fix. He could just set up the display to turn off but disable sleep. Most of the power being used is by the display anyway.
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.
Melita tried installing the Spectre Meltdown patches and now she's having issues with Windows. Leo says that the problem may be due to the antivirus companies not updating so that she can install it. Microsoft has to update Windows Defender with a patch to her registry that says it's ready. She tried doing a system recovery to reinstall Windows and now she can't do anything. Leo suspects that Melita may be having issues with her hard drive. Or her optical CD install discs have gone bad. It could also be a larger motherboard failure, like a dead motherboard battery.
