I recently installed Windows 7 and I can not open Windows Media Center. Before, when trying to open it, the error message "Windows Media Center has stopped working". Now no longer opens. I've tried as administrator, but it was useless. I believe that an update may have corrupted the program, such as 7 Service Pack 1, or the installation of Real Player may have major influence. I have not done a system restore and would like a solution without this step. Thank you.
