I've already installed Windows, installed all the required applications and device drivers, set all my required settings, etc.
I want to create an answer file that reflects all of the current settings for use with Sysprep.
However, any resources I look for show how to create the answer file from the Windows Installation media, and configure from there. Is it possible to create an answer file using what's already installed and take the configuration settings that have already been set?
Edit (in response to comment)
When I run sysprep without the unattend file,
sysprep /generalize /oobe /shutdown
When I next restart the computer, I'm asked to enter all the PC setup options again. I'm trying to avoid this. So in answer to the question as to why I'm running sysprep at all since I'll be deploying on PCs with the same hardware, I've read in various places I need to do this to "generalize" as otherwise the image I'm cloning from will have info specific to the PC (e.g. PC ID) I created the image on. Am I misunderstanding this?
Also I've found that when I use the above command line, after entering all the setup options, I get stuck on the "Just a moment..." screen forever.
