Since Device Manager shows all 4 cores, there's probably no
problem with Vista itself. For a second opinion, get CPU-Z
from cpuid.com. If it reports 4 CPUs, the issue is with Task
Manager only. The fact that TM sees 2 cores indicates that the
system is correctly identified as an ACPI Multiprocessor system.
A check with Device Manager will confirm this.
Besides CPU info, CPU-Z gives detailed memory info.
