ok thank you;) I'll test with the KB integrated my English was not good, I had not understood the need to delete the xml file and delete winsxs (cache) with vlite/rt7lite (I thought it was one or the other) thanks EDIT: I tested by integrating the KB, after installation folder "winsxs" is 2.13/2.17Go is much more than what I saw on this topic, it's normal? it is best integrated KB after installation, I think I used Vlite and after rt7lite (I need the 2 softs to do what I want) and I deleted the winsxs (cache) with rt7lite with vLite if I delete winsxs (cache), I can not delete DVD Maker, etc ...)
