Ok so here is scenario. I have previously successfully integrated various hotfixes, changed some default registry settings and set some tweaks using win toolkit. Everything worked first time, impressive. However I want to add more addons, add more registry defaults, change a few tweaks and add a unattended file. I noticed the integration process was very time consuming in my case took about 3-4 hours to update one image. Now I am back in the all in one integrator having made my adjustments, if I hit start on the previously modified image will it work? does it work quicker with previous changes already done? or do I need a fresh clean iso extraction when doing a new integration? apologies if this is already on faqs/docs. thanks
