My desktop doesn't have any problems with Sonar or DAW software applications. The only thing I do is disable the internet when I run Sonar.
However, I have a Dell laptop and I can't get it completely "clean" for recording so I installed a second SSD and installed Windows 10 home and Sonar (and the device drivers) nothing else. It is "good to go" for recording and the Latency Mon program shows it has no issues. The reason for installing the second copy of Windows/Sonar is that the Laptop is only used for on-site recordings and they are not very often. Most of the time the laptop is used for general PC so I didn't want to start taking out or disabling everything. I had the SSD and there was space for it in the laptop and that seemed to be the best option.
