Disable dual core

I have a program that isnt working right with dual core processing. I read on google that if I go to task manager and click processes, and find the process of the application that I can right click on the process and click set affinity and then click just 1 processor that this will work.

Has anyone tried this and after the machines is rebooted or turned off and then back on will it remember to run single core for this process?

I suppose you could always try it and see if it works, then reboot to see if it sticks. I've never had a program that doesn't actually run with multicore processors, so it's not something that I've needed to do myself.

yes, i've tried it.

yes, it works,

No, it will not remember it.. you can set the Affinity in the shortcut to the app, the command isnt coming to mind at the moment... google that :)

Just whatever you do, try not to disable dual core itself, i can be done by changing the "ACPI multiprocessor pc" driver in your system drivers, but from my experience, once you try and turn it back on your system becomes very unstable

changing that on the Fly will always make windows unstable, if you install windows with the "ACPI Uniprocessor PC" Kernel installed, it will work flawlessly.. just using one core.

looks like you've already sorted the problem but just in case, you can set affinity on the shortcut using either the addon 'imgcfg' binary, or the 'start' command.
