Let me start by saying I love this tool and it has saved me countless hours of work. I love the new SAD feature. One question I did have was on the DPsRootDel = "false" option. Am I understanding this correctly, the option is only if you are using a thumb drive or external drive for the location of the \D\ folder and if the option is not used all of the drivers are still installed on the machine and not removed. Other than that it appears to have worked perfectly on 3-4 machines that I have tried it on.
In response to markstrelecki's and OverFlow's post about SAD being intended for a machine that has all of its updates a tool that I uses that might help is c't update available here http://preview.tinyurl.com/yp993m It will download and create an iso of all of the Windows and office updates for XP, Vista, Server 2003 and multiple versions of Office. Work great if you dont have a WSUS server.
Again many many thanks to everyones hard work.
