    Is it possible to set permanent processor affinity? When you select 'Set
    Affinity' in task manager, does it just set it for that session, or every
    time that program is executed after? If not, is there a way to do this? We
    have a piece of software that is licensed per CPU core, not per CPU, so if
    we run it on a hyperthreading CPU, apparently we need 2 licenses, so we'd
    like to be able to set the software to only run on a single instance of the
    virtual processor, so we don't need 2 licenses.

  2. Just that session.
    Not that I know of.
    First, hyperthreading is not considered to be dual core, not even by Intel.

    Second, it should be up to the software to limit itself if there is a licensing

  3. Hi,

    Thanks Phil for greate information.

    I agree with Phil that hyper-threading is not dual-core and if you are
    using dual-core, you should contact third-party vendors for assistance of
    the license issue.
