Hi everyone, Sorry for my bad english, but im from Holland... that explains a bit I just downloaded a Vista Slipstreamed version (created by Muiz) wich include a lot of extras (programms, addons, etc.). My question is: can i strip some of those things off? And eventually, can i make it a REAL clean (but still activated) Vista version? I hope you guys understood my message and hope that there is someone who can help me.
