I need to replace a bad dll file

[Smith]

But i cant because its "in use" so how do i do this in dos?

Is it possible to rename it from dos or is it delete only.

thanks

You boot to DOS, or LiveCD (linux-knoppix or similar), delete the old, copy the new where it suppose to be, maybe in several folders as in the other method:
you could boot to safe mode and copy the fixed file over the bad one.

But, the file could be found in
many places (due to windows file protection etc.)
such as dllcache and system32 folder.

You just need to know what the file does and where it is, exactly.
Rest should be easy.
