Also welcome: any other suggestions for customizing a new Win7 install. So far I'm very pleased, the desktop is superfast, 6Gigs of ram, much faster than any laptop I've had and only 600$. I do want to avoid it slowing down over time, and definitely want to avoid it getting infected with malware. I live in Colombia and a lot of CDs etc. here are full of viruses.
