  1. I’ve been messing off/on again with this MCE problem – since I never use MCE, it was no big deal but it always bothered me that it worked, then stopped. After LOTS of searching, came across your blog and you managed to FIX my MCE. Thanks so much for taking the time to publish the answer…keeps me from pulling any more of my hair out. Ron

  2. THANK YOU SO MUCH!! I have been looking for days for a fix for my Media Center…..never had such an extreme issue……..It worked like a charm! THANK YOU! THANK YOU! THANK YOU! Microsoft could learn a little something from you!

    take care!

  3. Just want to tell you that this fix was AMAZING – Thank You!!!!! I have tried several sites that posted fixes for this, including Microsoft’s site, and NONE worked until this one. I have to say I was skeptical with all that typing and spaces, etc., lol, but this was perfect. So glad to have my MCE back!!!
