Hello,

No, wupdate.exe is only the web update "client". It checks checks whether a new version is available. If this is the case, it downloads and executes the "real" web update installer package. In the "real" update, you can detect if your application is still active, ask to shut it down, etc. and restart it at the end of the updating process (not under Vista/2008 please!).

Does this help?
