No. It's not built in. Only the i7's and i3's have hyperthreading.

Yep. It's kinda hard to enable something that is not there.

Games... 0%... actually HT on average decreases performance by 1% - 2%.

For programs designed to use HT, it depends on how well it is implemented. It can vary anywhere between 10% - 40%.

Programs that can use HT if it has been designed to do so.

Video encoding, 3D Rendering, image processing (i.e. photoshop), massive databases, financial and scientific modelling, file compression programs.
