PocketMatrix

i recently got my hands on an hp rx3715 and a bunch of apps came preloaded in the ram. Of course there was no option to remove these programs from the system so i manually deleted the applications from the ram ... the only problem is that the shortcuts still apear in the program listing w/ nothing asociated w/ it ( cause i deleted the program in the file explorer)

the question is where in the registry do i delete these broken shortcuts... thanks in advance, andy
