How do I disable a multi core CPU processor in a WIN8 computer?

1. First of all, we need to return to the traditional desktop location of the WIN8 computer, and then we press the Win+r shortcut on the keyboard to open the computer's running window, and then, in the Open Run window, we enter Mscon and click Enter, so we can open the System Configuration window of our WIN8 computer.

2. In the Open System Configuration window, we need to switch the interface to the boot section, after which we click on the advanced option below.

3. In the new window, we check the number of processors, and then in the Drop-down menu, we choose 1, and then click OK to save the settings.

With the above setup, we just need to reboot the Win7 flagship computer.
