Terry uses an Epson scanner/printer but he can't export it to PDF. An error occurs. Leo says that a PDF creation program could be an easy workaround that can talk to the printer. But it sounds like a corrupted driver. Terry should go to Epson.com to download and install all the latest drivers.
Windows 10 will be revealed on Wednesday of this week, January 21. It probably won't be out until Fall, but we'll learn more about it. There is a public stream of the event Wednesday morning at 9am Pacific time, and you can find out more about it at blogs.windows.com. We'll also have coverage of the event at live.twit.tv starting Wednesday at about 8:45am Pacific time.
Lauren called a week ago about her computer that wouldn't stop updating, and green lines she was seeing on the display. Leo told her to keep updating the OS. She said it took a week to update and the green lines disappeared. Now it runs perfectly. Leo says that's why he sets his updates to go automatically -- so they update as it goes.
Frank likes Windows 7, and he wants to keep that same look and feel when he upgrades to Windows 8. Leo says that upgrading to Windows 8.1 will allow him to boot to the desktop with a start menu, etc. But he can also use utilities from StarDock called Start8 and Modern Mix for $5 each. Leo says it's worth the money.
Mary has Windows XP and she needs to reformat her hard drive, but she has programs she can't replace. Leo says that she can look through her registry to find software keys so that she can reinstall them to reactivate them. But if she doesn't have the reinstall disks, she may be out of luck. That's why having an image of the hard drive is very beneficial.
Mike wants to know how to find all of the files installed by a program so he can remove them after he uninstalls that program. Leo says that the best way to uninstall a program is to use the uninstaller that comes with the program, or use the Windows 'Add/Remove' programs. Ideally the uninstaller should look at the manifest created by the installer and remove all traces. Sometimes those uninstallers aren't well done and it leaves some traces behind.
Leo says there's not much difference between the two. He uses a Mac Pro at home and likes it, but it's not very upgradeable, and any upgrades he could do would have to be external. On a PC, if he gets a tower case, upgrades are easy. Leo just got all of the video editors at TWiT Dell PCs and they will be moving to Adobe Premiere. The Mac Pro is expensive for what you get, and for pro video editors it's probably not the best solution.
Lauren's laptop has green horizontal lines. She tried to restore her OS and that seemed to fix the lines issue, but now she's dealing with Windows installation issues. Leo says that's interesting because the green lines usually point to a hardware issue. Leo says that it's important to install all the updates, otherwise she's vulnerable to security issues.
Ken has a old Intel iMac. Should he be reinstalling OS X occasionally to keep it running well? Leo says that he could, but it's not as important on a Mac as a Windows PC. This is largely because it doesn't have a registry. But he can do it if he wants, and it's really easy to do now. Once a year or two, it's a good idea to clear out the machine and start over. He should just make sure to back up his data first though.
Tyler wants to know about the hack for Windows XP that will allow it to continue receiving updates. Leo says it involves altering Windows so that it think its "Windows Embedded for POS." It requires a registry hack, though, and Microsoft frowns on it.
