System files replacement on-the-fly?

[Dels]

is it possible to replace system files on-the-fly? i want to replace some system files without another 3rd party tool, so are there any other methods? (cmd?batch?)

some info :

i want to make a "hacked win2k GUI" pack for my friends, and they didn't know anything about system files replacement (even they didn't know most command in cmd ) so i must did it by myself

thanks

It depends - most files can be unregistered, replaced, and then re-registered using the regsvr32 command, but there are some system files that are memory-mapped, and thus require a reboot to replace (the file loads into memory and is read from there, rather than disk, and only a reboot can unload it for replacement).

anyway i have found some method to made it replace

and still need restart (it's not a problem)

thank for the reply
