If you are an owner of a new multicore Intel CPU for example Intel core I7 and Windows 7 or Windows Server 2008 OS, you already might notice that some of the cores in your resource monitor are marked as parked. This is a new feature of windows 7/2008 operating system that is made to balance energy consumption by your CPU. So let’s say if you are performing some tasks that do not consume a lot of CPU power, all the cores that are parked will remain in that state. However, if you are running something that requires a lot of CPU power, all the cores, which were previously parked, will be placed in the active state (unparked) to perform the task. And after it’s done, they will be parked again.
All in all, this is a nice feature to save the energy. But if you decide to keep all of your cores active at all times, there is no way to disable CPU parking from the user interface or by running command prompt.
While searching the internet, I could not find any utility that will allow you to enable and disable the CPU parking without having to go and modify the registry manually.
So I decided to write one.
This utility will allow you to easily enable or disable core parking for your CPU. The first thing that you should do is to go to a resource manager to check if you have parked cores. The reason of doing so is that core parking is not enabled for all the multicore CPU’s. For example, if you have Intel Q9550 Quad Core CPU you may not see any parked cores at all.
Once you have started “Manage Parked CPU Utility,” you have to press “Check status button” to allow program to search registry for the keys and values that are responsible for the “core parking”.
After search has finished, you will see N number of rows in the list view control along with the Status that will describe if the value retrieved from the registry indicates that your core is parked. But as I said earlier, core parking is not enabled for all the CPU’ s even though registry value may indicate that cores are parked. From now you can press “Park All” or “Unpark All” buttons to enable or disable parking. Also, you can change a single row.
Note that for the change to take effect you will have to reboot your machine.
Also Utility should run with Administrator priveleges in order to be able to access registry.
This utility does not require installation.

Works perfectly fine Thanks@!
After running and restart my network monitor is gone in the tray. Stuff that removes this usually is mallware
I have a AMD A85600K CPU, and this program works perfectly :) Thank a lot :D
Or is what you's are referring to in Advanced Power Settings under Processor Power Management?
Where is the slider bar in Power Options? I've glanced around but didnt see it... I'm using Windows 7 Ultimate btw.
where are the downloads??? i did this on my old pc and it worked great!
TLDR: It worked for me on my Core2 Duo Laptop! BF4 Runs so much better.
I have an ASUS G72GX laptop. It sports an Intel Core2 Duo P8700 2.53GHz CPU, and a GTX 260m GPU. Before unparking my CPU cores, every 2-3 seconds while playing BF4, it would stutter. That rendered the game uplayable. I lowered all the settings to the lowest, and I would still get the stutter. After unparking my CPU cores, I have 30+ fps all the time, and no more stuttering! I've convinced my GF to buy BF4, but didn't make sure it worked on my laptop (she's using my laptop, I'm using my desktop). She bought it before I made sure it worked fine...and I was disappointed until I unparked my CPU cores. Now we can play together!
When I press "Check Status" it's seariching. After the progress nothing happend. It says "Ready" and its same like at the beginning. :( (System: Vista 64bit, CPU: Intel Core i5 - 3350P)
it works fine for i7 3770k
