    I have around 12 ASUS machines that are located remotely around the

    They were shipped with Hyperthreading turned on.

    We now know that Zenworks 6.5SP1b doesn't work with Hyperthreading.

    We want to disable Hyperthreading, however we have the BIOS password
    protected to keep the users out. We have no remote admin's at these

    Is there a way to modify the BIOS from within Windows? I could remote
    control the PC if that is possible, and make the change.

  2. It is the CMOS you want to modify, not the BIOS. Now any such access, will
    involve overriding the Windows hardware protection, which could leave
    holes in the security. That having been said, a tool like WPCREDIT, will
    allow this to be done.

    This is just idle speculation - can you disable a processor in Windows ?
    And would that be enough to make your applications happy ?

    Good suggestion. 3Ghz is overkill. Even at 1.5Ghz they are going to
    have enough CPU. I am assuming disabling 1 thread kills 1/2 the CPU?

  6. Doesn't work that way. The two logical CPUs share resources - if one is
    not running anything then the other has access to all of the shared

    I doubt disabling HT in the BIOS would give much better results than
    setting Windows to use only one CPU..

    Hyperthreading reportably decreases overall performance by ~10%, so I
    guess I'd get 90%. It's a mute point. The machines are overkill for
    our needs.

    I'm testing the software fix. If that works fine, I'll just leave
    hyperthreading on. Otherwise I will make these changes you
    recommended. I really appriciate the feedback. Thank you.
