Question: how to check if hyperthreading is enabled windows server 2012?
Answer: If you have a windows OS, open task manager and go to CPU section, in that screen if you see the number of threads say 4 but your CPU is dual core, it is hyper threading. If you have Linux, open system monitor or whichever task manager you have on your Linux, and go to resources tab. Check how many CPUx do you see.
