The only "tweak" if you want to call it that I have on my DAW desktop is the Power Plan set to High Performance.
I still disable Internet when I record or mix but nothing else. Resplendence Latency Mon shows system is clean.
However, I bought a Dell Inspiron 15 laptop for off-site (on site) recordings. I tried to clean it up for recording but was unsuccessful. The laptop came with an M.2 SSD and space for a laptop hard drive or full size SSD. I had a 256GB SSD so I installed that. I installed a "clean" Win 10, needed drivers and recording software - nothing else. It is set up as a Dual boot. If I want to use it as a regular PC I boot to the original Dell image, if I want to use it for recording I boot to the 2nd Win 10 image.
