Download PDANet for Android and Windows. Configuring it should be fairly simple. I tested it a couple of years ago just for the hell of it.

You need to tether you Android phone to the laptop with a USB cable. Maybe you can set up a wireless hotspot with your phone, but I don't know if PDANet will work like that.
Be warned, if your carrier notices that you are tethering your phone to the laptop they will charge you a tethering fee on your monthly bill; about $20 - $25 I think. The more times you use it per month the greater the chances of your carrier catching you.
