> I'd sooner switch completely to Linux
I do local IT. Word of mouth side job stuff. Its nice to remind myself why Windows is shit down in the trenches sometimes, and its a lot easier to manually uninstall a half dozen viruses and edit out registry rootkits for an hour after a week of coding.
I normally bill pretty standard in home support freelancer rates, $60 an hour with a minimum $80 to come. If I ever find a computer running Windows XP, I always offer and implore the owner (assuming they are not dependent on some software that has no Linux surrogate) to let me throw Lubuntu 14.04 on the thing. I do it for free, and offer up to three hours of tutoring also for free, because Windows XP is literally cancer. Its a tumor you don't know is there until it goes malignant and kills you by having some unpublished never to be patched exploit used to wreck your PC and steal all your personal information or lock you out. Its more unsafe than unprotected sex in a sleazy strip club.
Feature wise, Lubuntu matches pretty much perfectly, and even people still using XP often have Android phones, so the Lubuntu software center makes a lot more sense to people than have Play Store experience. Its not like anyone using these computers needs performance out of them - if they were trying to run a business or do anything intensive enough to require proprietary Windows only software they would have certainly updated the machine once in the last decade. They almost always are exclusively doing word processing and email, often not even web browsing because these are systems stuck with IE8 at best. And Lubutu does both of those things much better than XP ever did with auto-updating Firefox / Libreoffice and one click system upgrades every two years for LTS releases.
So yeah, switch to Linux, please. Your OS is hugely insecure and nobody is ever going to fix it.
