: Without the boot camp driver, your Mac is next to unusable -- Windows doesn't provide drivers for most of your Mac's hardware! Here's how to fix that. Insert the Boot Camp 4.0 CD, DVD or USB drive that you downloaded earlier and simply run "Setup.msi". Windows 8 users, again, need to perform some tinkering (which I describe below).

Done? Reboot! Now your Wi-Fi adapter, LAN, the graphics card, Bluetooth, the iSight camera, the sound chip and the trackpad should work properly.

: You're going full Mac on Win? Then let's make Windows 7 or 8 the default operating system, so you don't need to hold down the option key on your Mac to enter Windows: Right-click on the Boot Camp icon in your tray, select "Boot Camp Control Panel" and just click on "BOOTCAMP - Windows". Hit "Apply".

: If you're using a MacBook and just can't stand to press down on the trackpad, just select "Tap to Click" from the Boot Camp options menu. To further improve the trackpad, and download Trackpad++!

: Here's a weird bug that I've encountered on literally ALL my Macs under Windows and that still persists on my latest purchase, the 2011 MacBook Air. By default, the sound volume of all movies (iTunes, DVD, AVI, MKV, etc.) is way too low -- both coming from the speakers and the headphone jack. The solution: Go to "Control Panel", click on "Hardware and Sound", head over to "Sound" and right-click on your sound chip.
