HowTo: disable the Excel prompt for opening formats different than the extension
many web sites export tabular information from grids/tables into 'Excel' format. the file is not a true Excel format and actually contains X/HTML.  if the file is opened in Excel 2007 you may get a prompt that the file is in a different format than specified by the file extension.  if you regularly work with files like this, there is a way to disable this prompt, add a DWORD key called ExtensionHardening with value 0 to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security
it works straight away, no need for a reboot.
