switching hyperthreading on & off from the OS (not from the bios!)

[idata]

Hi

is it possible to switch HT off and on again from Windows operating systems?

My processor supports HT, and i can disable and enable HT from the BIOS. I know.

The question stems from the need to optimize certain and different CPU-intensive programs at certain times, without restarting the computer.

I know that this is possible from linux. but i didn't find a way to do it from windows XP/7.

alternatively, is there a way to temporarily disable and then enable single processorts? (again, from Windows, without going thru the bios)

thank you
