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.
Robert wants to know how he can build a bright light to blind a perpetrator if someone tries to attack his sister. Leo says that police LED flashlights are blindingly bright and they will work great. The Lume Cube is small (1 1/2" sq), and is extremely bright.
Here's some suggestions from the chatroom:
At CES Mercedes Benz says that they will have a self driving car by next year and are working with NVidia to develop it. Leo says that CES often announces things that don't happen for years, if at all. He thinks that it'll be 5 to 10 years before we see self driving cars on the roads as common place.
Dickie D is back from CES and he does the show differently than others, looking for crazy gadgets. The crazier the better. But he also found some useful things. Like the In & Motion Air Vest, which is an airbag for extreme athletes. You wear it like a vest, and it has sensors built in to measure what is happening. If something like you falling off a horse or motorcycle happens, the airbag will trigger. Cost is expected to be about $800.

Albert wants to know what smart watch is best for running. Leo says that for the recreational runner, the Fitbit is great. Many are also using the Samsung Gear. Leo also recommends not turning his back on the Apple Watch, as it finally has GPS built in.
When Sandy tries to stream Netflix on her Sony Smart TV, the app crashes. Leo suspects that the app has become corrupted, and it appears to be a common problem on Bravia TVs. A refresh of the firmware should solve the problem. The OS in Smart TVs is terrible, though, which is why Leo always recommends using a Roku, Apple TV, or even the PlayStation to stream Netflix.
Donald has an Acer Aspire PC running Windows Vista and he's getting a steady blinking light. Leo says that the blinking can mean something. It's like the "Power On Self Test." The motherboard battery may have died, and the light is telling him to replace it. That's the cheapest and easiest fix. If that doesn't fix it, he should look at his desktop power cord. Then he can move on to the power supply.
Jennifer gets a boot error when she turns on her computer. Leo says that it's likely that her hard drive has died. Leo says the good news is that hard drives are cheap to replace and really easy to install. Also, since Jennifer had upgraded to Windows 10, all she needs to do is download and install Windows 10 with the media creation tool and a thumb drive. A solid state drive would speed things up too. She should make sure to get one with the same kind of connector. It could be SATA or IDE, so she should bring the bad hard drive with her. This is why backing up is such a blessing.
A local TV news segment told the story of a girl who talked to Amazon Echo and accidentally ordered hundreds of dollars in toys and cookies through the automatic ordering feature. In doing so, the radio station triggered homes all over San Diego that have Amazon Echo to do the same thing. Leo says it's important to make sure you have parental controls on to avoid this, and to train yourself to not use the "A" word when talking about things it may mistakenly use to order for you.
Terry is an artist with Disney Imagineering, and she wants to know what's a good computer to for sketching and artwork. Leo says that Microsoft's Surface Studio was just announced and it's designed with artists like Terry in mind. It has a 28" tilting display, pen stylus, and a new Dial that will enable her to change colors and other options with a turn of the wheel.
