Windows 7 solves multi-core processor compatibility issues

With the development of science and technology, dual-core processors have become very common in our lives. Dual Core Processor refers to the integration of two computing cores on one processor to improve computing power.
You can open the task manager and click on the performance to view the working status of the CPU.

Although in most cases, dual-core work is our best choice. However, in some cases, dual-core processors have their drawbacks. For example, some older programs that run on a dual-core processor will have an exception such as a card machine.
In Windows 7, you can configure multiple core processors to use only one, or a few cores, while the application is running.
I will tell you the specific steps below:
Task Manager

CTRL+Alt+DeleteOpen the task manager, select the application option, left click on the application you want to set — — Right click —— Go to the process and you will be taken to the process options interface.
Then right click and select Set Relevance.

This way you can see the controls that control the operation of the CPU core. You can set the way for you according to your needs.

Look at the impact

You can open the disk defragmenter that comes with Microsoft, and then go to the performance options of task management, click on the resource monitor option below.

You can clearly see the operation of each core of the CPU, configure and view the different performance according to your needs.
Create Shortcuts
If you find that a running application is working faster on a particular processor core, and you use it often, you can set shortcuts to manipulate it. Let's start the disk fragmentation. As an example, I hope that I can help you a little.

win 7 system desktop
Start the disk defragmentation program, just think that it only runs on CPU0, you can create a shortcut with the following command:
C:WindowsSystem32cmd.exe /C start /affinity 1 Dfrgui.exe
If you want Disk Defragmenter to run only on CPU1, you can create a shortcut with the following command:
C:WindowsSystem32cmd.exe /C start /affinity 2 dfrgui.exe
If you If you want the disk defragmenter to run on both cores, you can create a shortcut with the following command:
C:WindowsSystem32cmd.exe /C start /affinity 3 dfrgui.exe
Start Disk Manager for the central Processor O and 1, if you convert the 3 after the affinity into a binary number is 011, then you want to CPU0 and CPU1,
If you have a quad-core processor, the affinity becomes 4 after running CPU2, If it becomes 9, it runs CPU0 and CPU3.
