If you’ve purchased a new PC in the past three years or so, chances are you acquire a multi-core processor configuration.

Newer systems are often equipped with a dual or even a quad-core processor chip. If this is true for you, you will want to check to be sure Windows knows to boot up with the number of cores set properly. Otherwise, you could be operating with only a single core active.To check, go to Start, then key in msconfig in the Search programs and files box. On the Boot tab that appears, select Advanced Options. Next, click to select Number of Processors and then select 2 or 4, depending on whether you’re using a dual or quad-core processor. Click OK and click OK again to exit the msconfig setup screen. You will then have to reboot for the changes to take effect, if any were made.
