Ever wonder how vendors like Dell create pre-installations of Windows Vista in all their PCs? Pre-installing saves them time configuring each operating system for different hardware.

If you are a reseller, even someone who sells PCs on a part-time basis, you will want to learn this neat little trick because it can save you time setting up different systems, partitioning and formatting hard drive with Diskpart, backing up hard drive using ImageX, connecting to network, troubleshooting using Windows-based programs, system recovery and many more.
