Installing Office 2007 does not put any shortcut on the desktop, you should
find shortcuts on your Start Menu > All Programs > Microsoft Office, and
possibly both a New Office Document & Open Office Document pinned to your
Start Menu
If you can see the shortcut in the Start menu then right-drag the shortcut
to your Desktop. When you release the mouse you'll see a menu. Select "Copy
Here" or it may read "Create Shortcut Here". If you see both options, use
the "Copy Here" option.
