Octoberfest7/BeatRev ? reverse-engineered prompt

Build me a safe demo app that shows how environment bound protection works for research and training, without actually running any real payloads. I want it to generate a Windows executable that, on first run, records some machine specific info, encrypts a harmless test blob with it, and on later runs tries to decrypt and verify that blob again. If the check fails, it should cleanly exit and delete only its own demo files.

Please keep it as a simple proof of concept with a small builder program, a staged setup, and a sample dummy file so I can see the full flow end to end. Make the code easy to read and explain with comments, and keep it focused on defensive education for analysts and blue team practice. If anything needs current Windows or compiler details, look up the latest docs online first.
