The quickest way to do this would be to open an adminstrative Explorer window (right-click an Explorer shortcut, the "Run as Administrator"). Perform your copy/paste operation from there.

You mention that you get an "Access Denied" message. This is likely because whatever file it is you are trying to replace is currently in use. which just increase the likelihood that you shouldn't be replacing whatever it is you are trying to replace.

However, your need begs the question: Why would you want or even need to paste anything into the System32 folder? It is protected in Vista and Windows 7 from casual file access in order to prevent problems.
