Like John says, it may be that at one time you could reinstall the OS, and it still occurs to those of us old enough to remember that old trick, but it is no longer a practical exercise. Last time I reinstalled an OS was when I was using Win2000Pro and I was experimenting with dual platforms. It's a lot of work to reinstall an OS--it kills an entire weekend, minimum.

I think my adjustments to the firewall seem to have helped on that computer. Knock wood, but we shall see.
