Personally I use a loader which looks at a version number embedded in the file name to determine the latest version.

I use to use another technique that is closer to what you describe.
In your exe, you have it check the server for a later version.
If one is found, create a batch file that has the copy command required and then the command to run your exe.
before quitting your program, run the bat file

The Bat file should have a small delay at the start to allow the exe to be cleared.
