Despite the widespread adoption of multi-core processors, some applications still use only one physical core. To fix this error, you must independently activate the work of the rest of the CPU.
Instructions
Step 1
Start by examining your operating system settings. Certain failures can lead to the fact that the OS will use only one core of the central processor to maintain its functioning. Press the Win key and type msconfig in the search bar.
Step 2
Press the Enter key. Wait for the window with the title "System Configuration" to start. Open the "Download" submenu by clicking the left mouse button on the tab of the same name. Now click the More Options button.
Step 3
Check the box next to the "Number of processors" item. This will allow you to manually set the initial number of active cores. Select the desired number from the drop-down menu. It should be equal to the number of physical CPU cores.
Step 4
Click the Ok and Apply buttons. After closing the working window, a new system message will appear. Click the Restart Now button.
Step 5
Now make sure critical programs are using the maximum available number of CPU cores. Press the keyboard shortcut Ctrl, alt="Image" and Delete. In the menu that appears, select "Start Task Manager".
Step 6
Open the "Processes" menu by selecting the tab of the same name. Find the program you are interested in. Click on its name with the right mouse button. In the opened window, select the "Set correspondence" menu.
Step 7
Select the checkboxes for the cores of the central processor that should process the information coming from this program. You can activate the item "All cores" or select certain elements of the CPU yourself. Click the Ok button after changing the parameters.
Step 8
Follow the same procedure for other programs. The system will automatically remember your choice. This means that in the future the operation of these programs will be provided by the selected physical cores.
