Task manager doesn’t show all CPU cores

I unlocked my AMD Phenom II X2 CPU to 4 core, but the Windows not show it.
The Task Manager not show it and CPU-Z show only 2 cores. But the Device manager and a BIOS shows all the 4 cores.

I found this solution for the problem, but it is not working. When I do these steps the Windows restarts, but nothing happens. Maybe because I use a Windows 8 and a never version of EasyBCD.

What can I do for working 4 cores?

You could try opening msconfig, boot options tab. Click advanced and ensure that the "Number or processors" checkbox is unchecked. This is the default setting but sometimes people change it based on misguided advice.

Unlocking CPU cores is always a gamble. In many cases the cores were locked for a reason, such as being defective.

Or put 4 cores in the same place.
