CPU / CPU Processor problems / Processor affinity

We appreciate the information you provided. Your processor is working as expected. CPU affinity is only showing CPU (0) since 1 processor is working at the moment. It's very likely that your computer is using a balanced power plan, so we suggest changing
your power plan to High Performance by following these steps:

• Right-click Start.
• Click Power Options.
• Choose High Performance.

In addition to that, we recommend installing the latest updates to keep your system current and secure. Go to
Start > Settings > Update & Security > Check for updates.

Some programs may also be automatically launching whenever you boot your computer, affecting the performance. To disable them, follow these steps:

• Right-click your taskbar.
• Click Task Manager.
• Under the Startup tab, find the programs that you don't need.
• Right-click the program and choose Disable.

You're also using your computer for a game that was designed to run on an earlier version of Windows, so it's possible that it's slowing down your computer. In this case, use the Compatibility Troubleshooter to find and fix problems with the program using
these steps:

• Click Start.
• Type Troubleshooting and press Enter.
• Click Run programs made for previous versions of Windows.
• Click Next.
• Choose the program from the list and click Next.

Let us know if you need further assistance with your computer.

 

affinity level CPU

I have a program that starts running too much CPU usage. The last time this program did this it was on an over the top 36 core something or other laptop, I like to call it the Unicorn laptop. To solve the issue I set the affinity level down to 8 cores from task manager details tab. I have a different laptop today which uses only has 8 affinity cores. For this one my program does not work correctly unless I set the affinity in the Task Manager to CPU 0. (uses too much CPU percentage).

In the previous laptop with 36 affinity cores I could set this in msconfig boot advanced options, so that it does it automatically when the PC boots. The problem now is when I try to do this through msconfig in my 8 core laptop so that it will do this automatically in startup it does not work. There is a dropdown for 1 to 7. I set it to one and reboot the PC and my program or the CPU usage does not take effect.

• Do other programs also show CPU 0 for Processor Affinity?
