Windows 10 "Set Affinity": how to force a program to use ALL processors?

[marcorocchini]

Hi, please be quite: I'm a CAT. Yes, a cat

Kindly I wonder, until now I need to manual set all processor from the "set affinity" of the task manager of a particular .exe program.

However I would like that a particular program is automatically set to be executed using all processors, and not only 1 by default. Consider that I need to set is by default in compatibily mode (Windows Vista SP2) and possibly I ask if it's possible include the usage of all processors in the general compatibility settings, possibly in the registry. Thanks

You can't use many CPU's (cores/threads) if your application is single thread type... Application may use many threads only if it is written to do so - that's why it is not easy to use modern CPU's. All you can do is use many single thread applications with assigned thread (core) to it.
Change application for multi thread version or accept limitations.

What test link are you using to assign a specific application to a specific core btw?

I've seen this type of posts many times. All I can recommend is - leave it to the Windows process/thread scheduler. It does a pretty good job at distributing workloads of single- and/or multi-threaded programs across the available cores (physical and virtual) efficiently. Don't fiddle with knobs you know very little about.
