Something much closer than nLite to this goal is Windows XP Embedded . Surprised most people haven't heard of it, since it's better than nLite at nearly everything (including deployment time) except user friendliness. After the install of the tools and database, I can get a functional build to install in five minutes. It also offers more customization, as it's XP Pro with everything componentized. For example, if you choose to remove certain parts of DirectX, instead of removing all of DirectX, you can remove DirectSound or DirectInput only.
