    That tweak is debunked:
    Yeah... maybe, perhaps the Registry method is the better way to go. Nevertheless, whatever it takes to prevent Windows from having to make extra 'calls' down to the 'engine room'!

    That tweak is debunked:

    Enable CPU Cores in MSConfig

    Some websites claim that Windows may not be using all of your CPU cores or that you can speed up your boot time by increasing the amount of cores used during boot. They direct you to the MSConfig application, where you can indeed select an option that appears to increase the amount of cores used.
    In reality, Windows always uses the maximum amount of processor cores your CPU has. (Technically, only one core is used at the beginning of the boot process, but the additional cores are quickly activated.) Leave this option unchecked. It’s just a debugging option that allows you to set a maximum number of cores, so it would be useful if you wanted to force Windows to only use a single core on a multi-core system — but all it can do is restrict the amount of cores used.

    Not in my case it wasn't like that, First time I installed Win8 "clean", I noticed computer running slower than before, checked with couple of programs and found out that only one core was active, only after setting number of cores with msconfig I got all 4 to run all the time. BTW my processor does not have that core parking feature, can only be set to wary frequency and with it the voltage according to demand.

    2. Select your start button.
    3. In the search box, type ‘regedit’ and press enter.
    4. Once your registry editor is open, select ‘Edit’ and ‘Find…’.
    5. Paste the above registry key in the box and select ‘Find’.
    6. Once it has located it, look for the keys on the right hand side labeled MinValue and MaxValue.
    7. Double click on each value and make sure they are both set to ’0′.
    8. Select ‘Edit’ and ‘Find Next…’.
    9. Continue to replace MinValue and MaxValue for each entry until you have replaced them all.
    10. Close the registry editor and shut down your computer.
    11. Power the computer back up.
    12. Core Parking should now be disabled.
    That's a bad way of doing it.

    disabling core parking at all times will fux0r up with your cache because everything will be run on the same core.

    Isn't "core parking" feature that all the cores are not used all the time ? When core is "parked" it means it is not used and switched off at the moment. So, when you "Unpark" all the cores they are all active.

    It is my understanding that if you use the "High Performance" setting on your Power Options, your Cores will never get parked no matter what.

    I've found this to be very helpful. I haven't had any issues so far been using unpark cpu for over a year. I follow this unpark cpu tutorial to be very helpful it basically show the step that edwin described but with screenshots.
