What's the difference between SysPrep and NewSid?

I'm setting up some Virtual PC images. I want to customize the machine with some pre-installed tools and then use this as a base for creating new machines.

What's the best practice for prepping the machine for use?

Should I use SysPrep or NewSid? When's the appropriate time for use and the contrast between them?

+3 A:

Sysprep includes the functionality of NewSID. It 'preps' the WIndows installation for imaging by stripping machine-specific things like the Machine name and SID from the installation. If you were not using Sysprep, you definitely would need to run a program like NewSID on each PC after deployment of the image.

In addition to doing the sorts of things that NewSid does, sysprep also resets/updates a number of other pieces of state in the installation to prepare for duplication/imaging. (Not updating this state can cause unexpected errors after deployment.) In general, it's a good idea to use sysprep...

NewSid seems to have some issues. I am aware that with Windows Sharepoint Services 3.0 and with technologies that built on them (Sharepoint Server 2007, Project Server 2007), you can run into issues outlined here:

Besides the answers already posted here it is also important to note that SysPrep is fully supported by Microsoft, while NewSID isn't.
