How do I replace a file that is in use?

[4wheelfurry]

I pulled my Shellres.96.dll out and replaced the icons, I replaced it back into Windows folder once using TotalCommander and it replaced fine.. So I edited more icons and now I treid to repalce it again and it won't let me, says "file in use".... I've tried ActiveSync, Total Commander, SKTools and a DLL exe written to supposedly do just that but none of them will wok being the phone is using the dll??? I'm stumped... Any advice?

Nvr Mind, I figured it out, renamed the \Windows\shellres.96.dll and then wrote in the new file and deleted the renamed file and soft reset. It picked up the new icons!
