12. Register Everything

It's no guarantee of great technical support, but if you register your PC with the manufacturer, as well as the software and peripherals with their respective creators, you stand a better chance of being recognized when the time does come to call for help—and you know that time will come. Getting a vendor to honor a warranty might depend on knowing when you bought or received the product.

Registering online is relatively painless; you're on the Web anyway, so you might as well. One downside is that registration can also put your name on endless mailing lists, so if that bothers you, deselect that option when signing up. Keep in mind that it's smart to be registered in case there's a recall—you don't want to be the only person walking around with a laptop battery that might catch on fire, do you?
