Well, at the end it seems I just needed an update. My old and good v1.22 wouldn't work anymore under Windows 7 ("driver could not be loaded", but Process Monitor v2.7 (Sep/2009) worked great as always, so I'm happy again. BTW, I apologize to the admins if I shouldn't have used this old topic, it was the one which seemed logic. I don't know if "unburying" or "ressuscitation" (sorry, I don't know the right words) is accepted here (it always varies from a forum to another). Anyway, if it shouldn't have been done, I beg that you accept my apologies and I promise I'll learn from that.
