Take the 2-minute tour ×  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?  share|improve this question Which
service pack are you using? It might be that you need the latest
service pack to support multicore processors... –  Mokubai Aug

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.  share|improve this answer Does that mean I cannot
see the usage of individual cores from task manager? But I
thought I have seen it before. Also how to identify the number
of cores in the processor? –  M
