The second processor core is usually enabled by default in the Windows XP operating system, but some programs require it to be disabled for correct operation. After that, certain difficulties may arise with returning to the original settings.

optimization program
Instructions
Step 1
Make sure the second processor core is disabled. To do this, open the Windows Task Manager by pressing Alt + Ctrl + Delete or Shift + Ctrl + Esc, and then go to the System Performance tab. Pay attention to how many parts the processor load window is divided into, if into two, then both cores are enabled and functioning at the proper level.
Step 2
In the case when you have only one of the two cores functioning in the Windows XP operating system, download and install an optimization program that tunes the processor. After installation, go to the hardware management of your computer and enable the operation of both processor cores. Be sure to restart your computer, even if the optimization program does not require it, do not forget to save the changes made beforehand.
Step 3
To test the operation of both cores of your computer, turn it on and run any game or program whose system requirements assume you have a dual-core processor. Start Task Manager and on the System Performance View tab, view the load of both items. It can be different for them, since the load is not always evenly distributed.
Step 4
Enable the second processor core by rolling back the motherboard driver installed on your computer. Prepare the driver in advance for subsequent installation, preferably an updated version. Reinstall the software, and then restart your computer.
Step 5
Check the operation of both kernels in the device manager. This sequence works in very rare cases. You can also try restoring the system from an earlier state, but in this case, the rest of the changes you made during the period of time will also be canceled.
