How can I identify Windows. I know that there would be the possibility of the Window handle, but this works only during runtime. If my User restart their programs a totaly new handle ist used.

But I need to save some Window related Data. How could I manage that.

I'll better explain it in an example:
Some of our Users are very old, but want to try everything. So if they get bored with Internet Explorer and Web-Browsing, they are browsing through the option dialogs of any application, and change this and that, so we thought about the idea to "stick" a little note to the dialogs and windows with short informations like, do not change the proxy settings, otherwise your internet connection wont work.

So I would save those notes in a Database but how do i know when i've to display them?

Exactly: how can I work out a unique, persistent identifycation of windows. you see, i can find out, that im talking to an application which was loaded from a binary called iexplore.exe but how can i identify the dialouges and so on.
