I tried JCL, but the one is not acceptable for me: edition function for XP is depended on registry nor
API or version. For example on my virualized XP it retunrs empty string, because in registry I have "Microsoft Windows XP".
Do you also think that JCL was entry point for TWindowsVersionsInfo?
BTW: Could you test it for me on W8 (I don't have it)?
