Windows XP Desktop icon menu size

We have a user who we had to replace his aging Windows XP machine with a newer machine running windows 7.  We are using the same exact monitors.  We had to use Vmware to virtualize his desktop as he had legacy apps that would not run under Windows 7.  For some reason he complains the icon size in his WinXP is smaller than it was on the other machine.  We tried the changing icon size to larger font and he felt it still was not good enough, is there anything else that can be done?  Running it at a much lower resolution does not work for him because then everything is distorted.  The monitors are running at the same resolution as they were on the older computer but he feels it was different looking as far as the menu of programs were concerned.

Any suggestions are appreciated
