One hardlink is locked. How do I remove the other?

I have several executables in different directories that are hard links to the same data.

.
|-- file 1
-- cache
-- foo.exe
-- bar
-- foo.exe <-hard link to .\cache\foo.exe
-- baz
-- foo.exe <-hard link to .\cache\foo.exe


If one of these is currently running, I can not delete the others. I execute .\bar\foo.exe and then try to delete .\baz\foo.exe I am told that the file can not be deleted. Killing the .\bar\foo.exe process is not feasible, as it is a long running and expensive task. But I really need .\baz\foo.exe gone, because I need the name for something else.

is there a way to break the link and get rid of .\baz\foo.exe?

You can rename baz\foo.exe (for example, to deleteme.exe), then delete it after the process exits.
