Hi all: I work for a small medical practice with about 45 employees in three locations. One of our doctors is refusing to move many of our PCs from XP to Windows 7. This doctor is borderline OCD and does not like anything to change, so any PC he touches cannot be upgraded. All the PCs I want to migrate all came with Windows 7 originally, and they do not run custom medical software, so re-imaging them to Windows 7 is trivial.

I have tried to reason with this doctor and have used all of the standard reasons why staying on XP is a bad idea, such as no MS support for security updates, Novell dropping full support (now self support), etc.. I need some more bullets to strengthen my position. Can you help? Or should I just give up and let things break?
