Any issues with changing number of processors on ESXi

In a VMware ESXi virtual machine there is warning by the box where you can change the number of processors a VM has.  The warning states that it can make your system unstable if this is done after the guest OS is installed.

Does anyone have any experience with this and if there would be issues increasing the count from 1 to 2 on a VM running Windows 2003 Server?

This was just what I was looking for, plus after reading I think I need to do more research as to if adding the additional CPU is something I really need anyway.  Thanks so much for the quick help.
