Windows doesn't have the Unix file system concept of execute
permission, no. If a file has the .exe extension and the first 512
bytes look like an appropriate header (MZ etc), Windows will happily
run it. With other extensions, similarly - just create a .bat file and
double-click it, it'll run the commands.
