I'm running Windows XP 32-bit on an Intel Q9650 quad-core CPU.
In Device Manager, I see four cores. It's OK. However in Task Manager, I can only see two cores. Are only two cores used? If so, why are there are four cores in Device Manager?
I'm confused. Does anyone know this problem? Is it related to 32-bit Windows? Perhaps I need to install some patches?
More information: I run Windows XP Embedded in KVM. It's convenience for me to do some simple tests. Are there any problems with XPE in virtualization environment? Or are there any differences between XPE and XP?
