Because this problem may affect more than one machine, it is also possible to create a scripting solution to delete the EXD files and run the script as part of the logon process using a policy. The script you would need should contain the following lines and would need to be run for each USER as the .exd files are USER specific.

del %temp%\vbe\*.exd

del %temp%\excel8.0\*.exd

del %appdata%\microsoft\forms\*.exd

del %appdata%\microsoft\local\*.exd

del %temp%\word8.0\*.exd

del %temp%\ PPT11.0\*.exd
