Hi everyone, This is driving me nuts, I know that I should know how to do this. But I've changed icons in shell32.dll and whatever I try I cannot over write the file as it complains about being in use, I've tried safemode and such like still no luck. Normally I'd just boot with a floppy and try overwriting it that way but it is on an ntfs partition and all my floppy boots don't see it. My question, how do I overwrite the file or make it so the system ain't using it for me to overwrite it? Many thanks, and I know it's a real no brainer of a question, but I don't know the answer apologies if it's the wrong forum. XP system b.t.w thanks!
