When you associate the bad.exe file with good.exe, that is, when you run the good.exe file in dos, you actually run bad.exe and generate a shortcut to good.exe in the directory.

C:\ > echo "This is test" > test.txt

C:\ > type C:\ bad.exe > test.txt:bad.exe

C:\ > mklink good.exe test.txt:bad.exe

C:\ > good.exe
