What happened
A retired Microsoft engineer recounts the story behind the famous leaked FCKGW Windows XP product key, revealing that the OS's copy protection mechanism used 10MB of encrypted Microsoft Bob data for validation. The article text itself is mostly site boilerplate, so the substantive detail is limited to the headline.
Why it matters
This is retro computing trivia with no practical takeaway for builders. There is nothing to change or decide based on this; it is an entertaining anecdote about legacy DRM architecture.
Discussion angle
Brief mention as a fun historical anecdote about how legacy copy protection schemes were built — not worth more than 2 minutes of segment time.
