From day 1, it interferes with Windows' DLL loader, unless special care was taken by the application developer. As time passes by, it leaves old, vulnerable versions behind, and opens a can of worms.
For applications which take extra care, such as recent versions of most executable installer frameworks, copying system DLLs to the application's folder has no effect; on older versions, it's arbitrary code execution.

Hardlinks and symlinks sometimes alleviate the problem of copying system files, but out of the box, Windows provides no high-level way for the user to make such links...

Well, clearly copying system DLL's is not the correct way to get programs running, I usually first try without tricks like this one, but if every other option fails (installing Windows from scrap is NO option, editing the registry to get a clean install and deleting all links to some unwanted piece of software is) that is what I try last before using restore to a previous installation from recovery where I go back at maximum 2 weeks to keep everything running, finally there is a monthly backup of a) everything and b) user-files.
But as a quick workaround...
