Tonight I updated my desktop computer to Windows' Office 2003 Service Pack 3.
Since doing so, my computer does not start up or work correctly.

All the icons on the desktop are not correctly displayed. If I try and
click on any of them, I get this error message for each and every program:

Windows cannot open this file.
File: Digital Line Detect (for example).lnk
To open this file, Windows needs to know what program created it.

It seems that the program is with the .lnk file association.

This is a most annoying problem, and one I need to get fixed immediately.
