I just converted a physical Windows XP x64 machine with 4 CPUs to a VMWare virtual machine with 4CPUs (on a ESX server) using the VMWare Standalone Converter.

Everything worked just great, except that the OS now seems to use only 2 CPUs (when 4 are installed, see the following image). This must be a Windows XP issue rather than a VMWare issue, but I can not really rule out any reason at this stage.

Device Manager vs. Task Manager

What can I do?

Wondering what more experienced ESX admins typically do... I just brought our ESX hosts up to 3.5 Update 5 (Yes, I know we're behind still).
