As mentioned in another post, sandboxing a browser might be helpful as well.

Other things one can do for privacy: Reinstalling your OS on a regular basis (at least once every 4 months maybe? using 'borrowed serial numbers' perhaps?), using different search engines, deleting cookies, using programs like Eraser (Portable) to clean up drives, using programs like TMAC MAC address changer, changing your hard drive serial number (PBDownForce can you say "Run As Administrator"?), etc.

Using encrypted drives/volumes and such might also be a good idea in case your computer might be compromised (TrueCrypt, SafeHouse)...stolen..borrowed..who knows.

Turning off browser "geolocation" feature might be a good idea too.
Concerning the rebuilding of the OS every so often, this is where VDI or virtualization can be most helpful .

Create a clean image. Clone it. Spin it up.
