However, "smart" isn't always "right." If you need manual control, you have to trick Windows into reapplying the affinity every time the program launches. This is the cleanest "native" way. You will create a batch file that launches your program, waits a moment, and then forces the affinity. windows 11 set cpu affinity permanently

Let’s look at how to make CPU affinity in Windows 11. Why doesn't Windows save affinity permanently? First, a quick reality check: Microsoft doesn't offer a "Save Affinity" button in Task Manager for a reason. Modern CPUs use heterogeneous architectures (P-cores vs. E-cores). Windows 11 is actually smarter than previous versions at automatically parking threads and moving workloads to the correct cores to save power or boost performance. Then you restart the application, and poof —your

Windows 11, like its predecessors, treats CPU affinity as a temporary suggestion, not a rule. By default, the operating system’s scheduler handles core distribution dynamically. But what if you have a specific need? Perhaps you’re running an old game that crashes on multiple cores, or a real-time audio application that needs a dedicated core to avoid pops and crackles. You will create a batch file that launches
