I was wondering if anyone know, how the autor of WPI made Runonceex run when you click Begin Install in WPI, without restarting windows. I could use that for testing purposes and don't want to start WPI every time. Many thanks for answer **EDIT** Also if kelsenellenelvian ever browse through this post, could you please post contents of you "WPI\Install\Regfiles" folder somewhere, when you have some free time. I read your config and found some great registry tweaks I would like to use myself. Many thanks
