How to Set affinity for an application in windows 10 / 11

How to Set affinity for an application on windows 10 / 11: – It doesn’t really matter whether you have a single-cored processor or a multi-cored one. What matters is how you set up your programs in such a way that the processor utilization is always efficient. Let’s take the case of our processor being quad-cored. A single application could be run by all the four cores at the same time. Don’t worry, though. This problem can be easily solved by setting affinity for an application on CPU. This simply means that you can actually assign processor cores to specific tasks as per your choice. You can determine which processor core should do which task and so on. If you take the case of an anti-virus software scanning your system, you might often have noticed the entire system slowing down. This could be because all the cores of your processor might be busy running this single application. Read on, to learn how to maximise your system performance by efficiently utilising the processor cores through affinity assignment.

STEP 4 A small window named Processor affinity opens up as next. Here you can check the cells corresponding to different CPUs. The cells corresponding to the processors which are allowed to run the specific application that you have chosen are to be checked. If you are okay with all the processors running the application, check the box corresponding to All Processors.
