Usually two is better than one. However, in this situation, that is not the case.
When deploying a recently-captured PC Transplant personality, it was discovered that there were 2 Microsoft Excel icons in the Quick Launch Toolbar, as shown in the image below. This was a problem.
To make sure this did not happen again, the PC Transplant personality template was configured to NOT capture Quick Launch toolbar settings. Then, when the personality was deployed, the items in Quick Launch worked correctly.
This only seems to be a problem when migrating settings from Windows 2000 to Windows XP. Migrator, beware!
