how to run examples is explained here:

But from your message it is not clear why you didn't manage to run.
Did you get some error message?

Was your installation successful (namely, did you build working executable? have a look to the
Quantum-ESPRESSO/espresso-x.y.z/bin directory)? If so, you need to set some environment variables
under cygwin according to what explained in the above link:
BIN_DIR: directory where executables reside 
PSEUDO_DIR: directory where pseudopotential files reside 
TMP_DIR: directory to be used as temporary storage area

On the side, although you should be able to easily install and make running Quantum-ESPRESSO
under cygwin + Windows, I would strongly suggest to try (if you have time) the much better, faster, friendly,
totally free, beautifully looking Linux operating system. You can download a live CD (just to try before installing it)
from www.ubuntu.com.
