Vista is 120% fail.
I'm using it right now and it constantly screws up on me, forcing me to fix it by wiping my computer completely.
As of right now, if I shut down or restart, anything downloaded, scanned, typed, etc. will get deleted.
Also the virus protection isn't too great either. It asks you 12+ times if you wanna do something, and sometimes after saying yes every time it still won't let you do it. You can shut that off, but doing so also means you shut off your protection.
This is a family computer, and my sisters used to put viruses on our computer when it was XP all the time because they're *******es. I'm still trying to convince my mom to switch us back to XP.
