Ok. Anyway, with latest test version, everything is OK. All updates are present, tested without nLite. HFNetChk reports all WMP updates are present, MDAC update not present (normal since I don't want it), and two files version greater as expected. And just a quick note : these files are post-installed: Q914798.EXE Q840374.EXE Q832483.EXE Thanks a lot for this version.
