As in previous versions of Microsoft Office, there’s an option in Office 2007 that turns on additional feedback sounds. The additional sounds needed for this feature to be activated, can be downloaded from this page at Microsoft's website.

Unfortunately the installer insists on having an older version of Microsoft Office installed and refuses to work if you have Office 2007. But there’s a rather simple solution to get it installed anyway. Here’s how:

1. Download the file sounds.exe from the web page above
2. Open an execute dialog by pressing the keys WIN + R or by selecting “Execute” from the Windows Start Menu.
3. Enter this command (note that c:\download in this example has to be replaced with the path where you stored the downloaded file):
   c:\download\sounds.exe /t:c:\officesounds /c
   This will unpack the installation files and store them in C:\officesounds
4. Go to the newly created folder C:\officesounds, execute sounds.msi and follow the instructions of the installer.

All what’s left to do is to turn on the sound feedback in one of your office programs. For example, in Microsoft Word you would click the Office-Button, then "Options" and "Extended", scroll down almost to the end of the dialog and turn on the option "Provide sound feedback".

Enjoy :-)
