How to identify unnecessary services and turn them off

Hi
I wonder if there is some systematic method to analyze and possibly optimize services in windows10.
I have tried a number of the off the shelf tools like cc ccleaner, iobit, iolo etc., but they don’t provide much improvement in performance. Plus HW optimization by adding ram and SSD.

Also I have checked the excellent overview by Shawn Brink.

Esp. how to turn off unnecessary services slowing down the system, mentioned in #19 of above link, quoting

19. Set Unused Services to Manual or Disabled

Services use processes that run in the background using part of your computer's resources. Check through your services with the help of the guide provided in this link, and stop and set to manual the services that affects features that you do not use or need to gain a tiny bit more performance.

WARNING: Disabling the wrong service could hurt performance, or even cripple Windows. If you do not truly know what you are doing, then it's highly recommended to not do this.

So how to identify unnecessary services and turn them off?

Hi dalchina
Do you have reference to

-noting your question is asked periodically, and an identical question was posted recently.

?

Here is a list of some of services this person feels are safe to disable. I just found it last week and I followed his advice. I only disabled a few of the services that were running. Most of the ones he mentioned weren't running anyway. So far so good. Use at your own risk and always have image backups.

BTW, this peron appears to be quite knowledgeable and conservative in his approach.
