Raymond Chen, a popular Microsoft blogger, recommends that you not worry about leaving keys because it's per-user data anyway and in many environments it's preferable to leave it behind. Definitely do not try to enumerate all user profiles to remove the keys for the other users because in the case of roaming profiles you'll likely corrupt a lot of stuff. If you want to remove all traces of your program, one alternative is to write your own SHMessageBoxCheck dialog and store the preference wherever you want.

Now you can use the font info however you want. Here's how to return a GDI+ Font corresponding to the MessageBox font selected by the user. Note that the height is always negative and always returns "world" units.

            MessageBox.Show(String.Concat(successCount.ToString, " windows tiled in ", vbCrLf, _

             ", ", inRect.Bottom.ToString), "Tiling...", MessageBoxButtons.OK, MessageBoxIcon.Information)

MessageBox.Show(e.Name " Renamed in " e.FullPath);

MessageBox.Show(e.Name " Deleted in " e.FullPath);

MessageBox.Show(e.Name " created in " e.FullPath);

By this property if you want to check file has been removed ,deleted from physical path then this will be true and you can check like if you have a tree view and you dont want to repopulate your tree view then use filesystemwatcher and repopulate the tree only when files have been changed,delete or rename. or you can throw a messagebox like above.
