Hi, I don't understand what you want to do. Do you have already slipstreamed SP1? Or before slipstreaming you want to rename file? If a file is opened by a program or pointer is set to a file, renaming do not work(you have to unlock file).
thx for sharing. Not working for me, tells me winamp is not installed but it is. Perhaps you should built in to "set path manual" to winamp install folder.
