The script from Bâshrat the Sneaky does'nt works I have tried it many times on all my differents drives and always in the same folder here is the proof.... I have Slipstream SP2 and all the fixes that you can see on this link aideinfo note that I have slipstreamed al the ones that show Slipstreamable The first unattended CD I have made, I have unzip with winrar all the files from MP10Setup.exe in my I386 folder and change my hive file Everything was running cool except that hanging window as you seenmy first post. Then I restart a new fresh installation without integrating any files from WinMedia10. Always the same problem. What I would like first is getting rid of that window media player wich i never use and by the same time getting rid of that window wich stop the installation. I have just starting to tried gunsmokingman's link and there are a few things that are not clear for me as I don't have any SvcPack.inf in my I386 folder only a compressed file SvcPack.in_ , but I do have a svcpack folder and also I don't have any program to make .sfx file from the 132 extracted files from MP10Setup.exe file. I have search many days to find an answer, all I have find is concerning WMP9 and not WMP10 and I would say nothing very clear for me a newbie TKS
