WAIK! WAIK! WAIK!

...Sounds like someone banging bricks together, doesn't it?

But really, WAIK is an acronym for " Windows Automated Installation Kit "

This is the toolset that IT Pros are going to want to get to know well, because it contains tools for imaging, installing, and deploying Windows Vista; including tools like IMAGEX and the System Image Manager. 

Wanna build your own WinPE (Window Pre-installation Environment) bootable disk?  Included are the tools that will let you do that.

It "RTW'd" (Released to Web) just two days ago.
