I am using a Dell Latitude 6410 laptop with Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz processor. I am not sure how many core it supports, but I assume it should be minimum of 2. But Windows XP task manager seems to identify only one core. Why is that?
Windows XP Professional can support up to two processors regardless of the number of cores on the processor, Microsoft Windows XP Home supports one processor. The OS sees a single CPU, it's up to the application to see the cores and then take advantage of multi-threading.
