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.

Hi,

It's possible that some of your computer's processors have been disabled, causing this slow performance. We'd like to learn more about your concern so that we could provide the proper resolution. We just have a few questions for you:

• Just to confirm, how many processors are on your computer? To check, click
