Nice, yeah same here one sysprepped and one pre-prepp, the one pre-prepped is also in audi-mode.
All software installed on the default user (audit-mode user) is available for all later userprofiles on that PC.
However due to licensing we only install freeware such as BGinfo, I found that accepting the install on the default user and placing a shortcut to our bginfo config in C:\Documents and Settings\All Users\Start Menu\Programs\Startup resulted in execution on logon even with new user profile.
Placing shortcuts in the default users desktop folder should result in icons on the new profiles desktop aswell, havent tried it tho.
We use clonedeploys filetransfer to move small licensed installations on to the new PCs. Like AV and VNC viewer.
What software are you deploying your large installations with? :0
I kinda would like a server like yours
