Ras, the problem is that in order to update the U3 partition, you need a program to do so. Currently, I only know of one for Sandisk drives (hence why everyone is recommending buying the Cruzers). If you would have carefully read the main post (or even skimmed over it), you would have seen that. That is why a5an0 is getting upset. He assumed that people would buy supported hardware for this. Until someone can find a way to reverse engineer the Kingston drives (which is possibly illegal) or Kingston releases a tool to update the U3 partition, Kingston users are kinda screwed.
The only other option is hope that someone will write a U3 Launcher compatible loader (I'm trying to, but my coding skills suck, and I'm having a few problems with VBStudio) and install it onto your U3 loader, but then, that removes the possibility of discreetness.
P.S. If people were to search Google for every question, there would be no use for message boards. These exist for communicating (that includes asking question)
