New to Windows, looking for performance/tuning advice

So due to frustrations with Apple's lack of attention to the pro market I've just built my first workstation pc! It has been a long several weeks of researching and purchasing, and a very long day testing the out of case build and then casing everything, and I'm happy to say it works!

Now I'm not a total newb to windows, I've done troubleshooting for clients and worked with pcs for various on site jobs. This is however my first personal system. After several tests with linX and some bios tuning I left the machine for a bit and came back to notice a lot of system services using my disks and network. Some of them were defender/mse related, but a lot of them were svchost instances, and also some asus stuff I installed as extended bios utilities (ai suite 2, not sure how I feel about it resource wise). Now I guess I'm just not used to seeing so many system services reported as osx likes to hide these from the user, but I'm wondering what the general recommendations for keeping the system lean are? I built this system for performance. One of the things I never liked about windows was that it always seemed to be doing lots of things on its own in the background. I'm curious what peoples recommendations are for slimming down background services, and any suggestions for performance tuning.

Any and all advice and suggestions are much appreciated!
