Did you know that the cores in your processor may not be used and therefore you can disable cpu core parking? Sounds crazy but the CPU cores are parked and not being utilized.
I bought a new hp laptop that has seven cores and I wanted to know if the operating system was actually using all of these cores. To my surprise there was only 3 of the cores being used. See the screenshot below. Every second core is parked.

Why is My CPU Cores Parked?
I do not know for sure but it could have something to do with power saving. But do I really want to save power or use all the available resources that all of my CPU’s can give me? Well I personally want to get use out of what I paid for and that means disabling parked CPU cores. I want them all enabled. I cannot be sure if this would speed up my computer but I was willing to give it a try.
