I'm sorry for posting on a year-old thread, but people reading this should be made aware that BuzMarius's batch script aside from the fact that it's not working (his method, killing the assistant process only does that, it kills it, but it doesn't prevent it from running at logon), it's also advertising a method that is easy to find using Google while the author of this amazing script worked hard to repack this into an amazing INF installer that excludes the ad-toolbars that accompany the original installer and is probably what most administrators would use anyway. I also had to thank Rico for sharing his work with us, as apparently nobody has thanked him yet. So what if this thread revives, the silent install script still works with the latest Unlocker So thank you Rico. I hope I'm not upsetting anyone too much.
