Hi Tripredacus, thanks for the reply, after reading my question, I'm not too sure if I've used the right terminology. I want it to run during that first boot where the user selects the regional settings, calendar date/time etc. I believe it is running a PE version of Windows, but not too sure if it has the .net framework running. Most things will be done with the unattend file, it is just that we also do a few things using a script which requires input from the end user and I would like to make the process prettier than an inputbox.
