Is there a way to disable hyperthreading in winXP by acting on the register with regedit?
i run a benchmark utility and it says that HT is enabled, but i want to try to disable it...
thanks!

sorry, not possible that easy. You have to change HAL to single processor, in device manager: Computer to ACPI-PC and disable HT in BIOS.

hi,
switch off "multiprocessor" or set the process affinity...

One must first disable it in BIOS then change the computer type (also refered to as HAL) to uniprocessor.
