Nope. No profiles. I run this like an office. Office doesn't let me install anything, so I don't let her. This way I am sure I get no viruses. I've had problems in the past and had to save data, reinstall Windows.. this is how I solved them. Avast, limited user, no problems for YEARS now.
Anyway, I don't even use that computer. I just don't ever want to have to fix it. I've got two side by side here. Built a dual core machine with 23" monitor she uses. I'm on a quad core with 27" monitor.
Have a 1 terabyte drive in the living room that plays movies and connects wirelessly. Everything virus scanned before it enters that too.
