The default configuration not only wastes global Internet resources but also introduces a multitude of security, privacy and intellectual property concerns.If you’re an experienced Windows system engineer, they may seem a little trivial.But even the most highly trained and savvy administrator can get in a hurry and make a mistake.I liken it to the days when automobiles had carburetors; a mechanic could fix most engine performance problems by fiddling with the choke—spritz a little WD-40 into the throttle body, charge and retire in the suburbs after a few years.
