In Window 7 Media Center, when playing in full-screen mode, pressing the Print Screen key produces a annoying ‘black screen’. Here’s an easy fix: 1. Open Registry Editor and navigate to following key: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Video 2. Create a new DWORD value called EnablePrintScreen and set its value to 1 3. Restart Media Center and try pressing Print Screen key again, and you’ll note that this time it captures the full image, even when protected content is playing.
