Sorry to be so late with my answer,but I've got a lot of problems during this week and couldn't spend time looking after this matter.Anyway,I encountered a further problem integrating the hotfixes;simply,the CD started booting and,after formatting,copying files and initializing, the system stopped,showing something like "the installation programme will be restarted" and restarting the PC.Actually,the installation was stopped and aborted. So,assumed that the error was evidently in the integration of hotfixes,first I checked the integration order (it was correct,by release date) after I disabled the "direct integration" in "advanced settings".This way I got through creating the right ISO;before burning I tested with Virtual box after I made the operation.I've just finished to boot the notebook and it's working well.No problems at all about WMP,I put it inside the ISO.About the use of Nero,I will make some tests when there will be some spare time,anyway I think that,almost for ISO files,ImgBurn is the right tool. Thank you a lot for your help,John. Giancarlo
