This question would likely best fit the General forum.
I will say though that this seems to be a very common problem across various models, and no-one seems to have found a single reliable solution other than to go through the inconvenience of disabling PT in the Task Manager after each boot-up.
Alternatively, you could try setting your PC to automatically kill the process on start-up. This can be done with a script or a pre-made optimization tool. Google for 'automatically close process on startup'.
Intel were asked on the support forums about disabling PTT last December, and a support team member said that it is a matter for the computer manufacturer, as they have the power to enable and modify this component. So you will likely have to work out a solution yourself with a method such as the aforementioned process kill.
