The below video shows how simply and quickly you can create a WinFE ISO. As you'll see in the video, all you need to do is...
1) Install Windows AIK
2) Download the WinFE batch files
3) Run "createfolders.bat"
4) Copy your forensic tools into a folder
5) Run "createwinfe.bat"
6) Burn your CD with the created ISO

It is great to see that the Windows Forensic Environment is being used as an accepted forensic platform by software manufactures, such as F-Response (blogged about running F-Response on WinFE) and WetStone.   WetStone has a version of their malware software available  on the WinFE system (although WetStone calls it the Windows Forensic Edition rather than Environment,  I believe they mean the same thing).

Colin Ramsden has been working feverishly on some modifications to WinFE that will appeal to everyone.    For some teaser screenshots, take a look here.   Bitlocker support, installing drivers while already booted to WinFE, clean shutdown that ejects the CD, and an easy to use Disk Management Console.  Believe it or not, Colin has even more to add.

Given the ability to make your own WinFE ISO with Colin's work, you surely will have one of the best forensic boot environments to date.
