INSIDE THE CRYPT
Installation on Windows is as simple as downloading TrueCrypt, executing the installer, accepting the license, choosing the Install radio button, and accepting default options for the last step.

As a cooperative soul, you give up your password to the first TrueCrypt volume. Finding some innocuous decoy data, the reviewing party is satisfied. But unbeknownst to them, you've utilized the Hidden volume option with a different password, and it remains safely hidden.
