I encountered this problem and followed some suggestions in some posts on the internet But none worked for me. I think the problem also results in zune setup failture, with the error code 0x8024200d, which requires the "windows 7 portable device update " to continue. I'm nearly mad at it this problem for past few days. so I hope an "expert" will help me to resolve my problem asap P/s: i dont have deep knowledge in tech, so please make the steps easier for me to understand. thank You so much in advance ! these are my CBS and dism log https://skydrive.live.com/redir?resid=D337EAE65856D855!361&authkey=!AN5WfKCdaeKMBX8 https://skydrive.live.com/redir?resid=D337EAE65856D855!362&authkey=!AIK3PKcE0mB-mEI
