Let's not forget that XXHighEnd is all (100%) about this, and the differences are huge (by means of countless settings combinations). Btw, the CPU load is a virtual 0% at 32/768 (16x upsampling from Redbook in real time). S.T. With previous versions of Windows I obtained a worthwhile improvement by running Windows in Safe Mode, which reduces the number of background processes running, as well as prevents non essential programs from starting. However, Windows 10 is a P.I.T.A. to do this.. Fidelizer by Windows X does similar with Windows 10 as well. If I wanted to create a poorer sounding audio file for comparison purposes I also ran a full Security scan at the same time. Even unplugging or switching off the cable to the Broadband Router resulted in a small but worthwhile improvement with Audio.

Other programs such as Ashampoo Win Optimiser also provide these kinds of facilities which also improves system response times , as does Norton Internet Security.
