When the Web becomes unreachable, it’s time to start digging into your router and firewall settings.
When your system’s port 80 is blocked, all http: traffic stops, and you’ll need to do a bit of cyber-sleuthing to learn the cause.
Device Manager — Windows’ underutilized repair tool — offers a fast, free way to repair common hardware misconfiguration problems.

With free virtual machine software, you can safely test the Windows 7 Release Candidate on your PC without risking your current setup.
You won’t get the level of performance in a virtual machine that you would with a standard Win7 installation, but VMs are still a fairly fast and easy way to create a software test bed.
The low number of reads and writes supported by USB devices means active caching on a flash drive is a bad idea.
Moreover, Microsoft’s much-vaunted ReadyBoost won’t improve the performance of most Windows systems, making this “speed-up” technology more trouble than it’s worth.
