How to enable hyper threading

Question

Dell Inspirion 17R 5737 with i7 Intel win 8.1 64 bit Looking at Task manager , there is only 4 cores. I want to enable hyper threading to have 4x2 cores when I look into task manager. I have also Inspirion 15r with 2 cores (i5) and can see 4 of them in task manager. Try to find solutions on net but without success. Please help... thanks

This system ships with the i7-4500U CPU, which is dual-core.  You don't have a quad-core CPU - so if you see four cores, hypertherading is enabled.
