Windows 10: Is there a way to pre-change a process cpu affinity?

I've been playing a game, but it uses all my cores and threads making my computer unstable, is there any way to change the priority of the process before it even starts? I've tried using a key in the registry to change the affinity of a process, I've tried to use a "NT AUTHORITY/System" Process explorer to change it, but no success, every error message says "Access denied".

Is there any way to really change the process affinity before it even starts so I can have a better experience?

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.
