Jerry has an Android mobile phone and after an update, he lost the use of both his cameras. Can he roll it back? Leo says that the upgrade probably didn't go well and failed, so try upgrading it again. You don't really want to go backwards because of security. Leo recommends doing a factory reset to wipe the phone and reinstall the OS. Be warned though that this will wipe the phone of all data apps and photos, so back it up to Google. But in most cases, that fixes the problem. If that doesn't work, the only way to go backwards is to root the phone.
Storm bought a computer in 2007 and has been updating it until Windows 10, where it won't upgrade because of her GPU. Now she's replaced her graphics card and Windows 10 finally installed! But she wants to know if she really has a 64-bit system. She looked at the specs and sees the phrase X64, which Leo says indicates 64-bit architecture. Upgrading also depends on how much RAM she has. So if she feels limited, then go to 64-bit in Windows 10.
Richard has an old computer running Windows XP. He'd like to boost the memory and hard drive. Leo says that most PCs are upgradable with off-the-shelf components, even the most proprietary brands. Go to Crucial.com or Kingston.com and use their memory picker. Input the model and they'll indicate exactly what is needed. Just remember though, running XP is dangerous to use online. Microsoft doesn't support XP anymore with security patches, and so it's just a target for hackers and exploits.
Eddie would like to update his Windows 8 laptop to Windows 10. Is it still available for free? Leo says no, but he's heard that others have been able to install Windows 10 with their Windows 8 key. So it's worth a try. Here's a great article on all the ways you can still get Windows 10 for FREE - https://www.howtogeek.com/272201/all-the-ways-you-can-still-get-windows-10-for-free/
LeAnn has an older Mac laptop that she wants to upgrade. Leo says the best thing to make your old Mac faster is to get an SSD drive. Adding more RAM will boost it as well. Should she downgrade to OS X Sierra? Leo says that High Sierra is actually faster, so there's no need to downgrade. But make sure to back up the existing hard drive before changing out.
Dan has a 2011 iMac and wants to know if he should upgrade to an iMac Pro. Leo says that the 5K iMac is still a great computer, but he doesn't know if he would spend the money to get the Pro version. One thought is to go with the new Mac mini and get a big monitor for it. June will be WWDC, and Apple frequently announces new iMacs in June, or in the fall. So if he can wait a few months, he can find out. If he can't wait, then Leo suggests looking at the Mac mini.
Joe's HTC smartphone finally died, and he's looking to upgrade the phone in his car to an Android system. Can he do that? Leo says that he probably can, as the screen mirrors the phone through the head unit. But there are a lot of limitations. Leo says that he'll need an Android Auto head end and he'll have to connect to it via USB, and it won't charge his phone either.
Jeff has a ten year old Dell XPS computer and it still works great. However, the newer games are only DirectX11 compatible and Dell says he has to get a new computer. Is there a card for him out there? The power cables are 6 slot and the new ones require 8 slot. Leo says he can get an adapter, but that age computer means it will be PCI, whereas the latest video cards are PCIExpress. Modern games use both CPU and GPUs in concert. And Jeff's power supply is probably underpowered.
Jack's iMac runs El Capitan, and his iMovie and Garage Band have stopped working. He has been told he has to upgrade to get them working back. But he's hesitant. Leo says that it's OK and you should upgrade. Apple isn't like Windows. You can safely go to Mojave, or at least High Sierra. Why did your apps stop working? That's a puzzle. Maybe your graphics card is too old? Or Apple may have just broken the connectivity. Upgrading to Mojave though is important for security reasons.
Rob has a process in his Mac called "User Event Agent" and he doesn't know what that is. Is it necessary? Leo says it is. It just monitors all of his activity. This includes mouse key presses, typing, etc. If he were to stop it, his computer would become unresponsive. He shouldn't really get caught up with what he finds in the Task Manager, especially when the processor and RAM are being used.
