How to update all the drivers to latest version(bootcamp) How to can I manually update all the drivers. I see my Nvidia card's support software always says new update available. Is it safe to update drivers from Nvidia site, some other sites(for other drivers) or Apple releases special type of drivers for there hardware and only those will be supported?
The important Apple drivers which Windows invariably doesn't have updates for are Facetime camera, Apple keyboard/trackpad/mouse, and the IR receiver.

Beyond these you can update any drivers that MS has to offer through Windows Update, and I've had no issues with downloading video drivers directly from nVidia. Always create a restore point so you can backtrack if you install something that doesn't work as well as it should, link to MS help page here.
