Windows 10: 2 Cores being used, not 4

I have a processor with 4 cores and because Windows is buggy, it only uses 2. Expected, but what does one do to solve such troubles apart from downloading Linux?

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

core unparking

I have a I5 7600 4 core cpu everything in the system is show 4 cores but there parked, I have the software for unparking them but when I use that it only shows 2 cores and that they are unparked but in the task window in performance it show all 4 cores
and that they are parked? so I'm not sure which is right and which is wrong since the program to unpark the cores is only showing 2 cores and not seeing the other 2 cores, but in the registry which is where it's looking all 4 cores are listed there. So my
main question then is there a place in the registry that you can change the cores to unpark them?

 

2 cores

Intel product page

https://ark.intel.com/products/80817/Intel-Core-i5-4460-Processor-6M-Cache-up-to-3_40-GHz

states it is a 4 core cpu.

Does win10 task manager or other software like cpuid's hardware monitor show 4 or 2 cores ?

The cpu is not a hyper thread version, so do not think that is the issue.

Win10 should see all physical cores. logical cores and threads if hyper threading is enabled.

Amd fx and some of the apu versions can have this.
