Issue with windows 7 Bing Dynamic theme shows only black background.

Issue: When using windows 7 and Bing dynamic theme suddenly after few days theme doesn't work and the only thing you have on your desktop is either only one image which doesn't change or you have a black background with theme sounds working fine.


Solution:  I tried everything that's mentioned in all the below posts but nothing worked properly.

The best solution I could find for this problem is to create a new user profile and migrate user profile data from old profile to new profile and your issue is resolved.
