Enabling the work of two processor cores in a computer occurs in several ways. Please note that many of these can damage your processor, so use only programmatic methods.

Instructions
Step 1
If your computer configuration includes a dual-core processor, enable the Hyper-threading function in the BIOS settings. To do this, restart it, at boot press the key that is responsible for entering this program. In most desktop computers, this is Delete, in laptops - F1, F2, F8, F10, Fn + F1, Delete, Fn + Delete and other combinations depending on the motherboard model. Enter your login password if required.
Step 2
Use the arrow keys to scroll through the BIOS program menu and familiarize yourself with its interface. Look for the Hyper-threading function, it may be in the processor settings, but it may also depend on your motherboard model. Place the blinking cursor on its position and change the position to On using the plus / minus buttons. Exit the program and save your changes.
Step 3
If your computer has a computer with more than two cores, and you only need to enable 2 of them, use special programs. Please note that they are often unreliable and will roll back changes to factory settings only after completely removing the operating system and formatting the local disk. This option is especially common when using Windows Xp on multi-core computers. The configuration of this operating system simply does not include the function of changing the number of working cores, since it was made at a time when processors were normal, so it may not be possible to roll back changes, even if you resort to third-party utilities. Only reinstalling on windows Seven will help here.
Step 4
If you need to change the number of cores for compatibility of the software version with the hardware configuration of your computer, use changing the attributes of the startup file of this program by right-clicking on it and selecting the compatibility mode with XP or Vista.
